A revolutionary sliding bearing material with added strength made of bronze and aluminum.
The copper stainless steel bearing material HLS20 is a stainless steel-based bearing material characterized by the inclusion of copper. During axial 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 more cost-effective than phosphor bronze while enhancing performance, making it a very user-friendly material. With the cooperation of a bearing manufacturer, a wear test was conducted for 17 days with 5 million reciprocations using SUJ2 for the shaft and HLS20 for the bearing, resulting in 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. Equipped with high melting point, high corrosion resistance, and dirt-repellent properties, making it ideal for high temperatures, corrosion, and marine environments. 3. Possesses high strength characteristics and excellent wear resistance and precision maintenance in high-load usage environments. 4. Usable without solid lubricants like carbon, significantly reducing processing costs associated with carbon insertion. 5. While priced similarly to bronze alloy materials, it offers superior wear and corrosion resistance compared to copper alloys. 6. Solves friction/wear issues in mechanical parts, reducing production costs and improving mechanical performance. 7. Can be used for long periods without lubrication, generating no friction heat, and can be downsized from existing bush sizes.

Company information
MTA Alloy Co., Ltd. is a casting manufacturer that has successfully developed an alloy of iron and copper for the first time in the world. The MTA alloy, which mixes familiar iron and copper, is truly the strongest superalloy in human history. 1. Copper Stainless S10 [Stainless + Copper] Copper is a metal with the strongest antibacterial properties. Copper stainless is an alloy that contains a small amount of copper in stainless steel, but it exhibits antibacterial effects equivalent to 100% copper. By utilizing this characteristic, many products are being developed to protect humans from invisible viruses and bacteria, such as those causing COVID-19 and food poisoning. 2. Bearing Material HLS10 Introducing a new bearing material. Similar to phosphor bronze, this copper stainless bearing can be used without oil and has improved wear resistance. We encourage you to try it out. 3. Thermal Mold Material MTAFeX2 The iron-based copper alloy MTA-FeX2 boasts thermal conductivity of 90W and achieves a surface hardness of HRC 60 with Edison Hard and HV 800 with Canniboron plating. - As "copper," which conducts heat and electricity well, is expected to see a significant increase in demand worldwide in the future, its price will continue to rise. Therefore, by using "copper alloys" made from inexpensive iron as alternative materials, we can contribute to the responsible use of limited resources in line with the SDGs.
