Hello,
I'm currently working at replacing a supply brass of discs. They are supposed to burst between 2500 and 2775 psi, and are made of C22000 copper alloy, 90% copper, 10% zinc (so it's technically a brass, but is called a bronze in the industry). Each disc is about 0.5" in diameter. The problem is that I'm having trouble finding a supplier that will provide the thickness needed (.006") in the quantities desired (15 lbs or less).
Because of this issue, I'm now looking into other alloys that aren't too dissimilar in composition. What properties are most important when trying to predict material properties, besides yield strength and ult tensile strength? Hardness? Temper? Composition?
At what point when varying the amount of zinc and including additives (such as tin) do the alloy's properties significantly diverge from the original alloy?
