Explosion-proof combined tools are widely used in flammable and explosive places such as PetroChina, Sinopec, CNOOC, military industry, coal mine, gas production, oil production, gas production, large chemical enterprises, refining, power stations, aluminum plants, metallurgy, storage and transportation, etc. for collecting granular flammable materials. Explosion-proof combination tool is made of aluminum bronze alloy and beryllium bronze alloy. These two materials will not produce sparks during continuous knocking, friction and impact. Also known as "non-sparking tool", the performance of explosion-proof tool is reflected in its good tensile strength. The tensile strength and hardness of aluminum bronze alloy can reach more than 25, and the tensile hardness of beryllium bronze can reach more than 35 degrees. It is a safety protection article.
