T8225D Explosion-proof flat shovel (protective sleeve)
【Material】 Beryllium Bronze, Aluminum Bronze 【Application】 Used for cutting metal wire in flammable and explosive places 【Manufacturing Process】 Die forging products 【Executive Standard】 German DIN6453 【Material Introduction】 Explosion-proof tools are divided into two materials: one is beryllium Copper alloy, 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 Beryllium-copper alloy explosion-proof T-tools are originally made of military materials and precious rare metals.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.
