Non-sparking Safety Tools are recommended for use where hazardous, flammable or combustible vapors, liquids, dusts or residues are present and should be used by all industrial safety programs. Non-sparking Safety Tools are an inexpensive investment for your company.
Application: non-sparking tools (safety tools) for hazardous areas to a wide range of industries and in a multitude of environments. Sectors where our tools often used include oil & gas, power plants, petrochemical, aviation, weapons manufacturing, bomb disposal, Ministry of Defence, pharmaceutical, pyrotechnics, breweries and distilleries, nuclear and local authority utilities.
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.
