Copper
Introduction To Bronze
Bronzes are copper-based alloys consisting mainly of 80 – 95% copper with other alloying elements, including tin, silicon, nickel, aluminium, iron, zinc, or manganese. Because of the wide range of bronze alloys and compositions, bronze is a versatile and widely used material. Bronze is a highly ductile material and exhibits relatively lower friction against other metals. Bronze is the most preferred material when high strength, hardness, wear resistance, and corrosion resistance are required, especially in marine applications. Because bronze is both strong and versatile, it is commonly used for sacrificial bushings.
Bronze bushings and wear pads have a long service life and are resistant to shock, impact, wear, and corrosion. To reduce friction and wear, they require an external lubricant, such as grease or oil, both during installation and operation. Kormax, with over 75 years of Foundry experience, is a reliable partner for large Bronze Alloy castings. Alloy selection, component design, manufacturing, and semi-finished material supply are among our areas of expertise. Kormax is well equipped for rapid and large-scale production due to its large inventory.

Kormax Bronze Manufacturing Methods
Kormax bronze is manufactured using finely controlled production methods of either extrusion, or more commonly continuous/centrifugal casting techniques. Continuous and Centrifugal casting methods ensure that hardness and strength are superior to sand-casting. It also means that the material has a fine grain structure and is free from porosity. Continuous casting can produce bars of solid round, hollow round, flat, and square amongst others from ½”/12.7 mm up to 18”/457.2 mm. Centrifugal casting is employed for making hollow round profiles up to 236”/6000 mm diameter.
Kormax can also obtain Extruded Bronze, which produces a highly consistent grain structure as well as higher tensile strength than other casting methods. Extruded Bronze is typically used for highly critical components such as aircraft undercarriage components and superyacht fittings.
Kormax can source the best Bronze alloy in the most optimal profile and size for your project and custom sizes and profiles are available upon request.
