MTA合金 Product Lineup

Introducing a new stainless steel called "Copper Stainless," which combines the rust-resistant properties of stainless steel with powerful antibacterial effects. MTA-S10 is the world's first copper stainless material, with over 10% copper added to SUS430. The main features are as follows: 1. Despite containing only 10% copper, it has antibacterial effects equivalent to pure copper. ➡ Certified by the Japan Copper Center as CU Star. 2. Unlike copper, it has excellent corrosion resistance. ➡ Copper rusts quickly. 3. It looks the same as stainless steel. ➡ 90% is stainless steel, so it appears silver. 4. Being iron-based, it is a safe, inexpensive, and secure material that contributes to SDGs. ➡ By promoting iron-copper alloys, we can cherish the limited resource of copper. While stainless steel is resistant to rust, it has almost no antibacterial properties, which has contributed to food poisoning incidents caused by the proliferation of O-157, Staphylococcus, and E. coli. MTA-S10 has a powerful antibacterial effect that can eliminate Salmonella within one minute.

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.

The Kiyomizu Ball (CS-10) will stop damage from algae and blue-green algae. Extreme heat is expected in 2024. Already, the highest temperature in February has exceeded 25°C, and algae begin to appear when temperatures exceed 20°C, rapidly multiplying once they surpass 25°C. If this trend continues, we predict that algae will start to appear around mid-March and begin to proliferate around the middle of March. Therefore, we would like to introduce the ultimate solution for "algae" and "blue-green algae" control: the MTA alloy original product, the Kiyomizu Ball CS10. This is a ceramic ball made by mixing a little of our developed copper stainless powder with a natural clay known as "loess," which is familiar in beauty products, and firing it at 1000°C. The copper stainless inside generates OH radicals that repel bacteria and viruses, effectively suppressing the occurrence and proliferation of algae from the root. Additionally, it is effective as an interior decoration for ornamental plants and in aquariums for ornamental fish such as goldfish and medaka. Various algae control products have been developed so far, but many have little effect, and many people may have given up. The Kiyomizu Ball is also very reasonably priced, so please take this opportunity to try it out.

Introducing Copper Alloy Tig Welding Rod MTA-YB5 A welding rod has been developed that makes it easy to weld materials that were previously difficult to join, such as iron and non-ferrous metals, or between copper alloys. This copper alloy Tig welding rod is used by over 100 companies. Please give it a try.

We would like to introduce application examples of the iron-copper alloy 'MTA9100 Metal Powder', developed by MTA Alloy Co., Ltd., which possesses both thermal conductivity and electrical conductivity. The circuit-printed sensors utilizing MTA9100/Metal Powder show no performance difference compared to the expensive silver nano powder traditionally used. Furthermore, they significantly contribute to EMI countermeasures by preventing noise interference. 【Examples】 《In the case of circuit printing》 ■ Circuit-printed sensors using MTA9100 powder ■ No performance difference compared to the expensive silver nano powder traditionally used ■ Significantly contributes to EMI countermeasures by preventing noise interference
