The annealing temperature for ZCuAl8Mn13Fe3 cast aluminum bronze is generally 760 ℃. Casting tin bronze cannot strengthen its mechanical properties through heat treatment because when the Sn content reaches 10%, the microstructure of tin bronze is no longer a solid solution but a compound, which is different from other solid solution bronze such as beryllium bronze and aluminum bronze that can be strengthened through heat treatment. Tin bronze needs to undergo low-temperature annealing after cold processing to improve the stability and elasticity limit of the elastic copper alloy. The annealing temperature of tin bronze rod and wire products is shown in Table 7-8, and the annealing temperature chart of tin bronze rod grades and specifications (diameter) is shown in Table 7-8. The annealing temperature for hard and soft Qsn6.5-0.48mm-25mmQsn7-0.2420-Silbronze requires intermediate annealing during pressure processing. What is the difference between tin bronze and lead bronze? Below, the editor of Hebei lead-free copper will introduce it to you: Bronze is the old name of copper tin alloy, now called tin bronze, which is an alloy composed of phosphorus and copper, called phosphor bronze.
