Non sparking bent handles are commonly used socket accessories in explosion-proof tools and can be name as offset handle or curved handle, the L-shaped handle is a transmission accessory for rotating socket heads and is mainly used in socket wrenches with fewer components.
Non sparking socket is also called safety tools or explosion proof tools.There are two types of materials.
1,Aluminum bronze,Al-Cu,aluminum,nickel,manganese,iron and other metals were added to the high purity electrolytic copper as matrix to form copper-based alloy.
2,Beryllium copper,Be-Cu,the copper base alloy was forming by adding some metals such as beryllium,nickel.
The thermal and electrical conductivity of these two materials are very good,beryllium bronze is non-magnetic and can be used in strong magnetic fields.
Performance
The material of non sparking tools: Al-Br(QAl11-4-4), Be-Cu(QBe2)
Be-Cu: the color is green lake,hardness is not less than HRC35,tensile strength δ b 105-120kgf/mm2;standard code GBEX ⅡC,suitable for hydrogen with concentration 21.0±2.0%.Beryllium copper alloy with anti-magnetic performance.
Al-Cu: the color is bluish yellow,hardness is not less than HRC25,tensile strength δ b 75-85/mm2;standard code GBEX ⅡB,suitable for ethylene with concentration 7.8±0.5%,GBEX ⅡA (propane 6.5±0.5%),Ⅰ（methane 6.5±0.5%).
Applications
