Program Description:The United States Mint has a requirement for coils of metal strip to be used as raw material for producing coins in the following denominations (5?, 10?, 25?, 50? and $1) for the United States Mint.
The raw material acquired must produce coins that are compatible with existing coinage in circulation within the vending, banking, commerce as well as the general public. The raw material breaks down into three separate alloys, one homogeneous and two 3-ply clad manufacturing processes. The five-cent (Cupro-Nickel) alloy is a homogeneous alloy composed of 75% Copper (Cu) and 25% nickel (Ni). The 10, 25 and 50 cent coins are made from a 3-ply composition (Cupro-Nickel-Clad), comprised of two exterior layers of 75% Cu - 25% Ni with a pure copper core. The $1 alloy (Nickel-Manganese-Brass) is a 3-ply composition, with the two exterior layers composed of Cu, Ni, Zinc (Zn) and Manganese (Mn) with a pure copper core.
Each of the 3-ply alloy compositions must be metallurgically bonded to ensure there is no possibility of separation within the layers. The Cupro-Nickel-Clad alloy and process was developed to replace previous coins, made from coining silver, and designed to function seamlessly in the vending industry. The Golden dollar alloy was developed to replace and function in the vending industry as the Susan B. Anthony dollar coin.
General specifications for United States Mint coinage strip:
Thickness: 0.041 in. - 0.0685 in.
Width: 12 9/16? - 13 ??
Coil size: 4,000 - 10,000 pounds, (nominal >7,000 pounds)
Estimated volume requirements:
