Bronze is an alloy of copper and other elements except zinc and nickel, mainly including tin bronze, aluminum bronze, beryllium bronze and so on.
Tin Bronze
The copper-based alloy with tin as the main alloying element is called tin bronze.Tin bronze is used industrially, and the tin content is mostly between 3% and 14%. Tin bronze with less than 5% tin content is suitable for cold working. Tin bronze with 5% to 7% tin content is suitable for hot working. Tin bronze with more than 10% tin content is 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, springs and other elastic components, as well as anti-corrosion, corrosion prevention and so on. Magnetic parts.
Phosphor bronze is another type of bronze commonly used in the manufacture of acoustic guitars and piano strings, and is also suitable for the manufacture of musical instruments such as cymbals, bells and gongs.
Copper-based alloys with aluminum as the main alloying element are called aluminum bronze. Aluminum bronze has higher mechanical properties than brass and tin bronze.
The aluminum content of aluminum bronze in practical applications is between 5% and 12%, and aluminum bronze containing 5% to 7% of aluminum has the best plasticity and is suitable for cold working. When the aluminum content is greater than 7% ~ 8%, the strength increases, but the plasticity decreases sharply, so more in the casting state or hot working after use.
Aluminum bronze in the atmosphere, seawater, seawater carbonic acid and most organic acids than brass and tin bronze has higher wear resistance and corrosion resistance. Aluminum bronze can be manufactured gears, bushings, worm gears and other high-strength wear-resistant parts and high corrosion-resistant elastic components.
The copper alloy with beryllium as the basic element is called beryllium bronze. Beryllium bronze contains beryllium 1.7% to 2.5%. Beryllium bronze has the advantages of high elasticity and fatigue limit, excellent wear resistance and corrosion resistance, good electrical and thermal conductivity, non-magnetic, and does not produce sparks when subjected to action.
Beryllium bronze is mainly used in the manufacture of important springs for precision instruments, watch gears, high-speed and high-pressure bearings and bushings, electrodes for welding machines, explosion-proof tools, marine compasses and other important parts. Bell bronze, another bronze alloy with copper and tin as its main components, is known for its acoustic properties and is ideal for producing clear and loud sounds in musical instruments such as cymbals and bells.
