Beryllium bronze has good overall performance. Its mechanical properties, i.e. strength, hardness, wear resistance and fatigue resistance of copper alloys in the first. Its electrical conductivity, thermal conductivity, non-magnetic, anti-spark properties of other copper materials can not be compared. In the solid solution soft state beryllium bronze strength and electrical conductivity are in zui low value, work hardening, strength has improved, but the conductivity is still zui low value. After aging heat treatment, its strength and conductivity increased significantly.
Bronze with tin as the main alloying element. Tin content is generally between 3 and 14%, mainly used for the production of elastic components and wear parts. Deformation of tin bronze tin content of not more than 8%, and sometimes add phosphorus, lead, zinc and other elements. Phosphorus is a good deoxidizer, but also improve fluidity and wear resistance. Tin bronze with lead can improve the machinability and wear resistance, plus zinc can improve casting performance. This alloy has high mechanical properties, wear-reducing properties and corrosion resistance, easy cutting and processing, brazing and welding performance, shrinkage coefficient is small, non-magnetic. Available wire flame spraying and arc spraying preparation of bronze bushings, bushings, anti-magnetic components and other coatings. Size specifications Ф1.6mm, Ф2.3mm. with high strength, corrosion resistance and excellent casting performance, has long been widely used in various industrial sectors.
(1) tin bronze to tin as the main alloying element of copper-based alloy called tin bronze. Tin bronze used in industry, most of the tin content between 3% and 14%. Tin content of less than 5% tin bronze suitable for cold working; tin content of 5% to 7% of tin bronze suitable for hot working; tin content greater than 10% of tin bronze suitable for casting.
Tin bronze is widely used in shipbuilding, chemical industry, machinery, instrumentation and other industries, mainly used in the manufacture of bearings, bushings and other wear-resistant parts and springs and other elastic components, as well as corrosion-resistant, anti-magnetic parts.
Beryllium bronze to beryllium as the main alloy component of a Wuxi bronze. Containing 1.7 ~ 2.5% beryllium and a small amount of nickel, chromium, titanium and other elements, after quenching and aging treatment, the strength limit of up to 1250 ~ 1500MPa, close to the level of medium strength steel. In the quenched state plasticity is very good, can be processed into a variety of semi-finished products. Beryllium bronze has high hardness, elastic limit, fatigue limit and wear resistance, also has good corrosion resistance, thermal conductivity and electrical conductivity, does not produce sparks when impacted, widely used as important elastic components, wear-resistant parts and explosion-proof tools.
