Advantages of5454 Aluminum Alloy Relative to 3-piece Rim Spinning
This alloy exhibits many characteristics that make it the best choice for rim spinning:
• ARS specified, and ARS approved
• High Magnesium and high Manganese Alloy
• Marine-grade material = high corrosion resistance
• Achieves its hardness and toughness during the spinning (forging) process
• No heat-treatment needed, therefore eliminating distortion
• The rims are true and round
• Ultimate tensile strength anywhere between 36KSI and 45KSI (same as 6061-T6)
• No heat-treat means there is no need to cut the rims (like 6061) to make them true
• No ‘thick-and-thin’ sections created from cutting
• No bolt breaking issues due to out-of-parallel assembly flange caused by cutting
• The rims achieve their full hardness/toughness during the spinning (forging) process
• Material hardness and toughness can be selectively placed within the rim
• Superb weld-ability
• Over 30 years, and over a million rims on the road
