Bronze alloys are the metals consisting of 80 - 95% copper with the balance made up of one or more other metals, such as tin, silicon, nickel, aluminium, iron, zinc or manganese. Bronze is a favoured material when strength and corrosion resistance are called for. Kormax casting capabilities include Continuous casting and Centrifugal casting. Continuous casting can be produce diameters from 1″/25mm up to 10″/254mm as well as square and rectangular profiles. Alternatively, Centrifugal Casting can achieve diameters from 8″/203mm up to 18″/3000mm spun bronze castings. In addition to these methods Kormax can also source Extruded Bronze. Extrusion achieves a more consistent grain structure and better tensile strength consistency than other casting methods. Extruded Bronze is generally performed for highly critical components such as Aircraft undercarriage components. Bronze is a versatile and commonly used material because it comes in many Bronze alloys and compositions. Bronze is strong and versatile, making it the material of choice for many sacrificial bushings. Bronze bushings and wear pads have long lifespans and resist shock, impact, wear and corrosion. They require an external lubricant, for example grease or oil, at installation and during operation to reduce friction and wear. Kormax is a trustworthy partner for large Bronze Alloy castings with over 70 years Foundry experience. Our expertise include alloy selection, component design, manufacturing and semi-finished material supply. With a large stock of Inventory Kormax is well equipped for rapid and large-scale production.
Leaded Bronze alloys include the addition of Lead, Tin and Zinc to create a range of alloys suitable for bearings, gears, sliding pads and other light-duty applications. Leaded Bronzes are light-medium duty strength with excellent machining properties and good corrosion resistance. A range of alloys are available such as C932 (SAE660) which has high amounts of Lead and Tin to create good lubricity. Leaded Gunmetal Bronzes such as LG2 (C836) have a increased amount of Zinc for slightly higher tensile strength.
Aluminium Bronze is a family of bronzes that is high-strength and corrosion resistant. Kormax offers a wide variety of grades and trusted alloy selection. Bronze is a versatile and commonly used material because it comes in many alloys and compositions. Bronze bushings (also called bronze bearings) are strong and versatile, making it the material of choice for many sacrificial bushings. Bronze bushings have long lifespans and resist shock, impact, wear and corrosion. They require an external lubricant, for example grease or oil, at installation and during operation to reduce friction and wear.
Phosphor Bronze is a high strength material that is often referred to as ‘gear bronze’. Components that are machined from PB1 are particularly durable in applications where high working loads and speeds are encountered, provided that there is good alignment and adequate lubrication. PB1 has good machining properties and good corrosion resistance to seawater and brine, making it suitable for pump and valve components. All Kormax PB1 Phosphor Bronze is manufactured using finely controlled continuous or centrifugal casting techniques to ensure that hardness and strength is superior to sand-casting methods. This also means that the material has a fine grain structure and is free from porosity.
Manganese bronze alloys contains additives of manganese, iron, aluminum and lead to achieve extra high strength and excellent corrosion resistant properties. These properties with the inclusion of lead for lubricity make it commonly used for bearings operating with heavy loads. Kormax also offers Copper Nickel Tin alloys as the premium bearing alloy. Copper Nickel Tin alloys have the highest strength and excellent galling resistance.
Standard Oilite bearings are impregnated with a highly refined mineral oil to ISO VG (SAE 30) having a high viscosity index and containing antioxidant, anti-rust and defoamant additives. Oilite® are sintered bearings often used in environments when high speed operation is required, in limited-space and variable-load applications.
