Product Description
Products Description

Super Invar alloy

4J32 alloy is also known as Super-Invar alloy. In the temperature range of -60~80℃, its expansion coefficient is lower than that of 4J36 alloy, but its low temperature microstructure stability is worse than that of 4J36 alloy. The alloy is mainly used in the manufacture of highly precise instrument parts requiring dimensions within the range of ambient temperature variations.
4J36, also known as Invar 36 alloy, is a special low-expansion iron-nickel alloy with an ultra-low expansion coefficient Main uses: Various instruments requiring dimensional stability, instrument parts, heated bimetallic passive layers, resonators Main features: It has a low linear thermal expansion coefficient in the range of 20-100℃

Company Profile
product factory precision nickel bar alloy 4j42 42ha for expansion alloy 42 rod and bar-3
Danyang Kaixin Alloy Materials Co., Ltd. was founded on April 18th, 2007, covering an area of 13500 square meters with a registered capital of 20 million yuan. It is a professional enterprise engaged in independent production,research and development of high performance alloy materials such as precision alloy, high temperature alloy, nickel-based special welding wire, corrosion resistant alloy and so on. It is Jiangsu Province private science and technology enterprise, small and medium-sized technology-based enterprise, employee entrepreneurship base, Zhenjiang Harmony Enterprise, 2017
Jiangsu Top 100 high-tech enterprises with the most growth and 2020 South Jiangsu National Gazelle enterprise in Independent Innovation Demonstration Zone.
Our company will add the most advanced 3.5 tons vacuum melting furnace and 5 tons atmosphere protection electroslag furnace to expand 2 nickel-based welding wire production lines, improving the production capacity of the company greatly in 2023. At the same period, the expansion project with annual 2000 tons output of nickel-based welding materials has been started and will continue to increase R&D investment. Since 2020, our R&D investment has reached 10 million.
At present, we have cooperated with Beijing Steel Research Institute Nak to establish the "National Steel Material Testing Center - Joint Laboratory" and cooperated with Jiangsu Provincial Science and Technology to establish Zhenjiang Microwave Communication materials Engineering Center and Jiangsu (Kaixin) Nickel-based Superalloy Engineering Technology Research Center.

From 2022 to 2025, our company will gradually transform from civilian to military, from mass products to science and technology products, and gradually move to the ranks of "high, refined, sophisticated, specialized and special" production. To this end, we will combine the existing research and development, production, testing and etc advantages to continue to expand our research and development team, continuing to make progress from exploration and testing.
