Explosion-proof tools to bronze and aluminum bronze materials as raw materials, bronze alloys, aluminum bronze alloy does not occur when the impact or friction sparks, very suitable for manufacturing the explosive, flammable, corrosive magnetic and occasions to use security tools. BeA-20C alloy containing 30% methane, oxygen, or 6.5-10% oxygen in air can withstand 561IJ impact, the impact of 20 times, neither of sparks and burning. 

 Explosion-proof aluminum-copper alloy synthesis tool is made of precious metals, melting, forging and made tools, the surface was yellow. Face hardness of HRC25 ° or more, the tensile strength δ b> 75-85kgf/mm, all other technical indicators have reached international advanced level. Flammable gases in ethylene (concentration 7.8%) were used to ensure the safety of continuous space, red (hit) hit, friction, sparks explosion not drop hammer
