The materials for explosion-proof wrenches in explosion-proof tools include aluminum bronze and beryllium bronze

Wipe the explosion-proof wrench after using the explosion-proof tool: The explosion-proof wrench materials include aluminum bronze and beryllium bronze. Explosion proof wrenches are made of beryllium bronze and aluminum bronze, and can corrode in media such as wet ammonia, ammonium salt, acetylene, wet fluorine, chlorine, ammonium chromium, potassium dichromate, and potassium hydroxide. In addition, some media will react with copper alloys after contact, forming explosive substances, such as acetylene steel formed by the combination of acetylene and steel. In the above situations, if it is impossible to avoid using in humid environments, the operating speed should be accelerated and the working time should be shortened to avoid the danger of serious corrosion. Wipe clean in a timely manner after use, and it is strictly prohibited to install and store it together with corrosive media

Explosion proof performance of aluminum bronze explosion-proof tools: suitable for ethylene gas with a concentration less than 7.8%, standard specification GBEX IIB, hardness not less than HRC 25, tensile strength δ B75-85 kgf/mm2

Beryllium bronze explosion-proof tool explosion-proof performance: Beryllium bronze explosion-proof tools have magnetic explosion-proof performance and are suitable for hydrogen with a concentration less than 21%.

. The hardness of the standard specification GBEx shall not be lower than the tensile strength of HRC 35 δ B 105-120 kgf/mm2
