A new material for high-performance sliding bearings with enhanced strength made of bronze and stainless steel, 【MTA-HLS20】, has been born.

The copper stainless steel bearing material HLS20 is a stainless steel bearing material characterized by its copper content. During shaft movement, trace amounts of copper precipitate on the surface, serving the role of oil, making it a groundbreaking oil-less bearing material that reduces friction heat. Moreover, it is much more affordable than phosphor bronze while improving performance, making it a very user-friendly material. With the cooperation of a bearing manufacturer, a test was conducted using SUJ2 for the shaft and HLS20 for the bearing, resulting in a wear test of 5 million reciprocations over 17 days, with a maximum temperature difference of +3°C.
Features of MTA-HLS20:
1. A copper stainless steel alloy containing 20% copper, with excellent castability and machinability.
2. It has a high melting point, high corrosion resistance, and dirt resistance, making it ideal for high temperatures, corrosion, and marine environments.
3. It possesses high strength characteristics and excellent wear resistance and precision maintenance in high-load usage environments.
4. It can be used without solid lubricants like carbon, significantly reducing processing costs associated with carbon insertion.
5. While priced similarly to bronze alloy materials, it outperforms copper alloys in wear and corrosion resistance.
6. It solves friction/wear issues in mechanical parts, reducing production costs and improving mechanical performance.
