We stock Bronze in the following forms
With up to 5 different grades of Phosphor bronze & also a huge range of aluminium bronze bar available on the shelf, as phosphor bronze stockists our stock range has helped us supply companies within the marine, automotive & aerospace industry to name a few.
There are 4 main types of Bronze – Gunmetal, Leaded Bronze, Phosphor Bronze and Aluminium Bronze of which P+P stock the following:
PHOSPHOR BRONZE – 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 – 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. For example, 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. And, silicon improves the machinability, corrosion resistance, ductility and hot workability.
