The difference between Beryllium copper and Aluminum bronze 

When selecting the right alloy for your non-sparking, non-magnetic safety tools, you have two choices: copper beryllium tools or aluminum bronze tools. 

1.Hardness:Our aluminum bronze alloy tools have a hardness of 25-30HRC. If your application requires a tool with higher hardness rating, copper beryllium equipment, with an HRC of 35-40, is a good choice. 

2.Magnetic properties Aluminum bronze equipment features low magnetism due to its minimal ferrous composition. Beryllium copper tools have a more non-ferrous composition, so this equipment is safer for applications that require non-magnetic properties.

3.Composition:Aluminum bronze alloy tools: Al: 10%-12%, Fe: 4.5%, Ni: 4.5%, Other: 0.5%, Cu: Balance;

Beryllium copper alloy tools: Be: 1.8-2.3%, Co + Ni: 0.4%, Other: 0.5%, Cu: Balance
