Be-Cu Vs Al-Cu

Non-Sparking Tool Materials: Aluminum Bronze Tools vs Copper Beryllium Tools

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 is an aspect to keep in mind in this selection process as well. 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.

Packing & Delivery
Packing Detailed: Each piece of non-sparking tools pack in a polythene wrapper, then some pack in a carton with a layer of shock bubble film.
Delivery : By sea, or by air or express as the customers' requirment.
