Without doubt, brasses and bronzes are the most widely utilised family of materials on the planet. This technology is a leap ahead for brass alloys. "Low-Cost High Entropy Brasses" (HEBs) with their unique alloy composition are up to 20% cheaper to produce and have the potential to change the market landscape for standard bearings, bushes, gears and cogs made of traditional brasses.
These alloys consist of varying mixtures of copper, nickel, manganese, zinc, aluminium and tin allowing for specific tailoring of cost, strength, wear and corrosion resistance and display the same self-lubricating properties as typical brass.
- Lower $/kg of constituent alloys
- Similar machining characteristics and higher forming ductility than standard brasses (suitable for forging)
- Harder than traditional brasses giving superior/longer wear capabilities
- Superior mechanical strength and lighter than traditional brasses leading to less material required to produce a component and higher component efficiency
- Standard bearing housings and bearing bushes for heavy automotive applications
- Bushes/bearings for small electrical appliances and hand held tools.
- High performance, low-cost gears & cogs for motorised/rotating consumer electrical appliances
UNSW is seeking a partner to license this technology and work with the Lead Researcher Dr Kevin Laws, School of Materials Science and Engineering to further develop it for specific applications.
