Features :
Beryllium bronze work surface hardness HRC35° or more, tensile strength δb>105-120kgf/mm2, aluminum bronze material hardness not lower than HRC25, tensile strength not lower than δb 75-85kgf/mm2 base, its technical indicators all reach The advanced level of similar foreign products. In the flammable gas space, the continuous use of the hydrogen space is safe and safe, and the impact (collision), friction, and drop hammer do not produce spark explosion. The beryllium copper alloy explosion-proof tool also has a special anti-magnetic function, which can be used normally in a working environment with a magnetic field. It can effectively prevent the flammable explosion caused by the friction between the tool and the work object and the impact, and ensure the national property and personal safety!
