Cast Aluminum Letters: The Ultimate FAQ Guide

Cast aluminum letters are made from molten aluminum metal that’s poured into molds.

The result is a finished product with a smooth surface and sharp edges.

After cooling, the letter can be polished and painted to create an elegant look.

This guide is intended to help you with why you should choose Cast aluminum Letters, the disadvantages, how they’re manufactured, and much more.

What Are The Benefits Of Cast Aluminum Letters?

Cast aluminum letters are some of the most popular exterior signage options.

The main reason why cast aluminum is such a widely used material is that it has some excellent properties that make it ideal for outdoor use:

Durability – Cast aluminum letters are very durable and hold up well in various weather conditions. Because they have been sand-cast, they offer more strength than standard sheet metal or flat cut metal letters.

Corrosion Resistance – Aluminum is naturally corrosion-resistant, but you get even more corrosion resistance when you add an alloy to create a casting.

Light Weight – Unlike solid metals like steel or brass, cast aluminum offers the same strength with a fraction of the weight.

This makes mounting these letters much easier and less expensive as it requires less support materials.

Recyclable – Aluminum is one of the most recyclable materials around; up to 95% percent of aluminum can be recycled without losing its natural qualities.

Versatile Surface Finishes – Because there are so many alloys available for cast aluminum, this material can be finished in any color imaginable and treated with either matte or polished finishes.

It is easy to maintain cast aluminum once installed, except to wash off dirt or debris once in a while with mild soap and water.

Also, check after severe weather if any damage has occurred that needs to be repaired.

They’re 100% recyclable and eco-friendly! This means less waste in our landfills and more money saved on energy costs for replacing them.

Choosing cast aluminum is not only a greener option, but it’s also more cost-effective than other materials like bronze or copper due to its longevity.

How Are Cast Aluminum Letters Made?

The process for casting aluminum letters begins with a mold. It may be made of wood or rubber, but in the case of aluminum letters, the mold is made from resin.

First step is to cast the letter in an epoxy resin. The resin sets up hard and creates a negative of the letter.

The negative is then used to make a silicone mold used to cast the aluminum letters.

Also, the silicone mold is created by pouring silicon into it and turning it over to pour out the excess.

Once cured, the silicon takes on the exact shape of the letter negative.

The next step involves mixing up a batch of molten aluminum alloy using pure aluminum rods and lead, zinc, or copper alloying agents.

Besides, the molten metal is then poured into each cavity in the silicon mold until it is full and overflows.

The molten metal cools slowly over time and shrinks as it does so.

This creates a void inside the metal cavity that will allow air to escape when more material is added later on during finishing operations.

Where Can Cast Aluminum Letters Be Used?

You can use cast aluminum letters for a variety of things. You can use them as interior doors, furniture, or wall decor.

Not only that, but you can use them in your home theatre room, office space, and garage.

They are also suitable for use in restaurants and bars because they give a classy touch to the place.

Is There a Recommended Thickness Of Cast Aluminum Letters?

There are 52 stock fonts available for cast aluminum letters.

The fonts come in sizes ranging from 2″ to 24″ (depending on the font) and are 3/8″ to 3″ deep for RIBBON DEEP fonts.

In addition, the overall thickness depends on the height, style, and font chosen and how deep you want the letter to be.

Tiny letters can be made as thin as 1/8”, while larger letters can be 2” thick.

This general increase in thickness with height has to do with the visual appearance of different-sized letters.

Smaller alphabet letters look good at thinner depths, while large letters need more consistency to “fill out” and look visually balanced compared to their size.

What Are The Available Cast Aluminum Letters Surface Finishes?

The most common surface treatments used on aluminum lettering include:

Polished: This process creates a high gloss or shiny finish on the surface of the sign material.

It can be applied by hand polishing or machine polishing with buffing wheels (rotary polishers).

The finished result can range from ultra-smooth to nearly mirror-smooth.

Polishing leaves a slight sheen to the surface of the letter, which gives it a shine and makes it more attractive to some people than that an anodized finish.

Polished surfaces will not maintain their sheen over time; however, they can be polished again with some success.

Anodized: This process is used for signs with fine detail and lots of contrast between the letter and background color.

This is  because it creates a hard protective coating on the metal surface that resists corrosion from rain, snow, and steamy climates (for example).

It also creates a “chalky” appearance on the sign’s surface, making it look very nice.

How Do You Choose Right Cast Aluminum Letters Font?

There are many factors to consider when choosing a font for your company’s logo, but the most important is legibility.

It’s hard to read from far away if the font has any type of decorative feature or if there are too many variations in the letters themselves.

Other things to look for include:

-Font size. The bigger your business gets, the more critical it is to keep text from being too small.

-Line height. It’s essential with longer words and short sentences that appear in different fonts throughout a document.

-Text color. Use black text on a white background if possible (or make sure your computer can display it).

How Do Cast Aluminum Letters Compare To Cut Aluminum Letters?

Both cast aluminum and cut aluminum letters provide a high-end look that will impress your customers.

However, the two types of letters differ in several important ways.

The most significant difference between cast and cut letters is how they are made. Cast aluminum letters are created by pouring molten aluminum into molds.

This technique allows for more detailed and ornate letter designs, making these letters ideal for companies seeking to convey a high-end brand image.

Cut aluminum letters are fabricated by using a CNC router to slice through metal sheets.

Because the fabrication process is more straightforward, cut letters tend to be cheaper than cast letters.

Are Cast Aluminum Letters Durable?

Cast aluminum letters are highly durable and will last for a lifetime with proper care.

Treating your cast aluminum letters with respect is the key to their longevity.

Which Are The Sizes Of Cast Aluminum Letters?

Cast Aluminum Letters are available in many sizes. The size of letters is determined by the font the customer chooses.

A range of font styles is available to help customers select the right style for their needs.

Are Cast Aluminum Letters Suitable For Signs?

Cast aluminum letters are the best option for small to medium-sized signs. These letters come in many styles and sizes.

Their durability, low weight, and high weather resistance will help you create the signs you want.

How Much Do Cast Aluminum Letters Cost?

Cast aluminum signs are highly durable and functional, but they can be expensive.

The cost of your sign will vary depending on the size of the letters you’re purchasing, the type of metal used in the casting process.

The material used to protect the letters during shipping and installation, and other factors.

However, it all depends on which company you choose. If you have a lot of customization requests, you might end up paying more than if you have less customization requests.

And if the company’s products are well-known, you might find the price of their products to be very high.

Which Materials Can Replace Cast Aluminum Letters?

Plastic molding is great for replacing your older font letters. It’s easy to cut and drill, it doesn’t look fake at all, there’s no polishing involved, and it costs much less than aluminum.

Steel is another popular choice because it’s durable and weatherproof. You can weld it, form and shape it as needed, and then use painting or spray-on enamel finishes.

Fiberglass is also an excellent choice if you intend to paint or stain your sign because it’s less likely to fade or peel than some other materials.
