Safety Double Ring Ended Spanners
Share:
- Suitable for flammable and explosive environments, including petroleum and liquefied gas, petrochemical, gunpowder, chemical, winery, spray booth operation, gas pipeline, leather processing, electric power, military, pharmaceutical, ship, tank, aerospace, mining and other kinds of flammable and explosive working environment.
- Explosion-proof tools are made of Be-Bronze bronze and Al-Bronze aluminum bronze materials with special characteristics of high mechanical strength and no sparking due to frictional impact.
- Aluminum bronze: hardness: HRC20-30, tensile strengthσb75-85kgf/mm2
- Beryllium bronze: hardness: HRC30-40, tensile strengthσb105-120kgf/mm2
- Beryllium bronze has stronger torque and hardness than aluminum bronze. Suitable for use in places where explosion-proof safety levels are demanding.
- Phosphorus bronze: lower hardness than beryllium bronze, good fatigue resistance, can be used for electrical and mechanical materials, higher reliability than ordinary copper alloy products.
