The main differences between beryllium bronze and aluminum bronze explosion-proof tools lie in their material composition, physical properties, usage environment and application scenarios.

Material composition

Beryllium bronze: It is a copper-based alloy made by using high-purity electrolytic copper as the base and adding appropriate amounts of elements such as beryllium, nickel, etc.

Aluminum bronze: It is a copper-based alloy made by using high-purity electrolytic copper as the base and adding appropriate amounts of metals such as aluminum, nickel, manganese, iron, etc.

Physical properties

Hardness: The working surface hardness of beryllium bronze reaches HRC 35 or above, while that of aluminum bronze is HRC 25 or above.

Tensile strength: The tensile strength of beryllium bronze is 105-120 kgf/mm², while that of aluminum bronze is 75-85 kgf/mm².

Explosion-proof grade: Beryllium bronze explosion-proof tools have an explosion-proof grade of EXIIC, while aluminum bronze explosion-proof tools have an explosion-proof grade of EXIIB.

Color: The surface of beryllium bronze explosion-proof tools is yellowish red, while that of aluminum bronze explosion-proof tools is silverish yellow.

Magnetism: Beryllium bronze has no magnetism and is suitable for environments with strong magnetic fields, while aluminum bronze has magnetism.

Usage environment and application scenarios

Beryllium bronze: Due to its high hardness and non-magnetism, it is suitable for usage scenarios with strict magnetic field environments, such as operations in strong magnetic fields.

Aluminum bronze: It is suitable for general explosion-proof environments, such as gas stations and oil refineries.

Manufacturing process

Casting process: Traditional manufacturing process, with low cost, but the product density, hardness, tensile strength and torque are lower, and the service life is shorter.
