All about Bronze

THERE ARE FOUR MAIN TYPES OF BRONZE, GUNMETAL, LEADED, PHOSPHOR,AND ALUMINIUM.

GUNMETAL.

Gunmetal's are the most widely used of the casting alloys offering good corrosion resistance, modest strength and good cast-ability They are used for pumps, valves, bearings and bronze statuary. The addition of Zinc to Tin bronze greatly improves the cast-ability and the addition of up to 8% lead will improve its bearing qualities.

LEADED BRONZE

Lead is added to bronze to improve its machinability There are alloys that have a lead content ranging from 1 – 30%. However the higher the lead content the more of a reduction the lower the mechanical properties such as strength and fatigue resistance. On the other hand the plasticity increases. Which is important in such applications where the mating material is a soft steel, which could be scored by harder materials.

PHOSPHOR BRONZE.

PP Non Ferrous supply the following Phosphor Bronze Products : LG2/CC491K, PB102, PB2, SAE660, PB1C

The addition of small amounts of Phosphorous to Tin Bronzes typically of about 0.4 – 1% increases the hardness, wear and strength of the alloys. Sometimes small amounts of lead are added to improve the bearing properties. This will reduce the strength but be of advantage where extra rigidity would be an advantage.

ALUMINIUM BRONZE.

PP Non Ferrous supply the following Aluminium Bronze products. CA104/CW307G and AB2/CC333G

Aluminium bronzes are alloys made from 77 – 93% copper and Aluminium from 6 – 12%.

Smaller amounts of nickel, iron, manganese and silicon are added to exploit different metallurgical characteristics for different applications.

Adding Aluminium to copper improves the strength and corrosion resistance.

Nickel. Adds to the corrosion resistance and raises the proof stress.

Manganese. Stabilizes the metallurgical bête phase and improves the tensile strength.

Iron. Refines the grain size once again adding to the strength.

Silicon. Improves the machinability, corrosion resistance, ductility and hot workability.
