T86405 Dipped Wrench,Hex key
【Material】 Beryllium Bronze, Aluminum Bronze 【Material Introduction】 Explosion-proof tools are divided into two materials: one is beryllium copper alloy, and the other is aluminum copper alloy. (Also known as beryllium bronze and aluminum bronze) 1. Aluminum-copper alloy explosion-proof tools are made of precious and rare metals, smelted and forged, and the surface is yellow. The hardness of the working face is above HRC25°, and the tensile strength δb>75-85kgf/mm2. Continuous use in the space of flammable gas ethylene (concentration 7.8%) ensures safety, and no sparks and explosions will be generated by impact (impact), friction, or falling weight. 2. Beryllium-copper alloy explosion-proof T-tools are originally made of military materials and precious rare metals. The surface is also yellow after being made into tools. The hardness of the working face is above HRC35°. The tensile strength δ b>105-120kgf/mm2. In the space of flammable gas hydrogen (concentration 21%), it can be used continuously and quickly without any spark explosion due to impact (bump), friction, or falling hammer. Beryllium copper alloy explosion-proof tools also have a special anti-magnetic function. It can be used normally in a working environment with a magnetic field. 3. The handle passed the flame retardant test. The handle passed the 500N pull-out force test. Passed the 10000V extreme insulation withstand voltage test. The handle passed the impact resistance test.
