Aluminum Stock for Signage

Signage is commonly used by businesses as a form of advertising and is highly effective because of its wide audience reach. While wood and plastic can be used, aluminum is usually favored for its durability and other properties. Its versatile nature makes it ideal for indoor and outdoor use. It can also be custom-cut to accommodate any wording and signage size.

With numerous aluminum sheet sizes and compositions available, it may be hard to decide which will suit your specific needs. Champagne Metals can help by guiding you through our aluminum specifications. Here’s more information on aluminum sheets for road signs.

Aluminum Sheets for Road Signs

The aluminum sign industry is large and competitive. With signage companies fighting to gain market share, they’re rapidly evolving and finding ways to attract potential clients with improved, state-of-the-art signage materials and other offerings. Most maintain that aluminum is the best material, and with good reason.

Road signs endure constant exposure to extreme weather and must withstand these elements. Suitable aluminum blanks for signs provide the ideal canvas to imprint branded advertising. We’ll explore the advantages and disadvantages of aluminum sheet below.

The Properties of Aluminum Sheet Used for Signs

Learn more about aluminum sheet’s benefits and considerations to decide if it will suit your application needs.

Aluminum sheet has several benefits, including:

  • Exceptional weldability
  • Workability and bendability
  • Superior form retention
  • Profound impermeability
  • Impressive fatigue resistance
  • Outstanding thermal conductivity
  • Unparalleled corrosion resistance
  • Impeccable use for decorative anodizing

Some disadvantages of aluminum sheets include:

  • Cold working is often the only way to strengthen the aluminum sheet’s temper since heat cannot be used
  • Some sheet sizes and thicknesses experience poor machinability, meaning extra power is needed to cut the aluminum

Aluminum Sheet Temper

Aluminum alloys’ temper or hardness is measured by O, H and a number. O is the softest grade. The number followed by H determines the hardness, with increasing digits signaling a harder temper. For example, H38 is one of the harder alloy tempers, while H12 is softer.

Our aluminum tempers range according to the metal sheet’s dimensions and thicknesses.

Aluminum Sheet Chemical Properties

The chemical properties of the different types of aluminum sheet vary, with some being almost purely aluminum and others having larger amounts of additional components. Our purest aluminum composition is the 1100 aluminum sheet, comprised of 99% to 99.9% aluminum. Others like our 3004, 5083, 5182 and 6061 products contain traces of magnesium, silicon, copper, iron and further residuals that dilute the aluminum’s pure consistency.

Aluminum Sheet Mechanical Properties

The mechanical properties are measured by the following:

  • Yield strength
  • Tensile strength
  • Hardness or temper
  • Fatigue/shear strength

The tensile strength is related to the temper and measured in megapascals (MPa), while the Brinell scale denotes hardness as HB. The mechanical properties of each aluminum sheet product we supply vary based on their application requirements.
