Proof tools introduced

The explosion-proof material of the tool is a copper alloy, so that the the proof tools body of friction or impact tools and objects, short heat generated is absorbed and conduction due to the good thermal conductivity of copper and almost no carbon qualities, another reason because the copper itself is relatively soft, good concessions, friction and impact is not easy to produce tiny metal particles, so we could barely see the sparks, explosion-proof tools, also known as non-sparking tools. Explosion-proof tools made from beryllium copper and aluminum bronze as raw material, beryllium copper alloy, aluminum bronze alloy impact or friction sparks, very suitable for the manufacture of explosive, flammable, magnetic and corrosive occasions security tools. The the BeA-20C alloy containing 30% of oxygen or the 6.5-10% methane empty oxygen withstand 561IJ impact energy, the impact of 20 times, none of the spark and the combustion. The main Scope: petroleum refining and petrochemical industry, coal mines, oil fields, natural gas chemical industry, gunpowder industry, chemical fiber industry, paint industry, fertilizer industry, a variety of pharmaceutical industry. Oil round and LPG vehicles, aircraft, warehouse operating inflammable and explosive materials, potroom communications machine assembly shop, the tool does not rust, wear diamagnetic place on. Aluminum-copper alloy explosion-proof tools is synthesized precious rare metals, smelting, forging made the tool surface yellow. HRC25 ° face hardness, tensile strength δb> 75-85kgf/mm other technical indicators all reached the advanced level of similar foreign products. Are to ensure safe continuous use space in the flammable gas ethylene (concentration 7.8%), red (hit) strike, friction drop hammer produces no sparks explosion.
