Tin bronze alloy is bronze with tin as the main alloying element. The tin content is generally between 3 and 14%, and it is mainly used to make elastic components and wear-resistant parts. ROCHO provides tin bronze melting processes, and tin bronze induction melting furnace, equipment repair and parts replace, coil repair facilities, and installation services.

ROCHO INDUCTION offers different types of steel melting furnaces, medium frequency induction furnaces, flat furnaces, electric arc furnaces and ladle refineries, to suit the different output and technical requirements of our customers.

ROCHO INDUCTION offers high frequency quenching technology for the inner wall of the workpiece to increase the surface hardness and service life of the workpiece. High frequency hardening equipment is suitable for quenching workpieces inner wall such as concrete pump pipe, cement pump pipe, gear inner ring and mould bore.

ROCHO INDUCTION provides high-strength bolt heat treatment process and bolt induction  heating equipment, bolt forging equipment, bolt induction hardening equipment. After bolt heat treatment process, the hardness, wear resistance, strength and service life of the bolt will be greatly improved .

ROCHO INDUCTION provides chain heat treatment solutions, through induction hardening, annealing, normalizing, tempering, carburizing, nitriding, and other process, the wear resistance and hardness of chains can be effectively improved.

The main methods of surface heat treatment include flame quenching and induction heating heat treatment. Commonly used heat sources include oxygen acetylene, oxypropane, induction current, laser, and electron beam.
