0.8 * 150mm Copper Based Alloys Brass Strip / Tape Cu70Zn30 C26000 For Cartridge Case
Brass Strip / Tape Cu70Zn30 / C26000 Size:0.8mmx150mm For Cartridge Case
Brass is a metal alloy made of copper and zinc; the proportions of zinc and copper can be varied to create a range of brasses with varying properties. It is a substitutional alloy: atoms of the two constituents may replace each other within the same crystal structure
C26000-The "work-horse" of all copper alloys, Cartridge Brass as it is often termed can be readily formed into thousands of different parts and has the strength to perform many useful functions. The unique properties of C260 have allowed this alloy to find application in everything from bullet cases and automotive terminals to door trim and even jewelry. With a warm yellow color and ability to accommodate severe forming/drawing this alloy is one of the most versatile commercial metals.
