Announcing the Availability of New High-Conductivity, High-Strength Corson Alloys
― Achieve Further Improvements in Both Strength and Conductivity over Previous Products ―
JX Nippon Mining & Metals Corporation (President: Seiichi Murayama; “the Company") has begun sales of new Corson alloy sheets, offering further improvements in conductivity and strength from earlier products.
The Company applies original alloy development expertise gained from years of experience, combining this with precise process control techniques, to develop and manufacture Corson alloys (Cu-Ni-Si alloy) having both high strength and high conductivity, and has been supplying these products to the market.
The demand to reduce for generated heat and power consumption has risen particularly with the view of avoiding the increase in current flow for advanced functions like quick charging, smaller connector terminals, and so on. In answer to the demand, the Company is providing the two new products announced here. Both have superior properties compared to the existing Corson alloy C7025, and offer customers the optimal alloy for their individual needs.
The main features of each product are described below.
1. High Conductivity Corson Alloy NKC4820 (CDA: C64810)
Corson alloy NKC4820 was developed as a high-conductivity alloy ideal for connector terminals that need to handle increased current flow. While maintaining the same level of strength as the C7025 alloy (0.2% offset yield strength: around 700 MPa), conductivity has been raised to 60% IACS. This is a major performance advance, as an alloy combining these strength and conductivity levels has yet to be seen anywhere else in the world.
2. High Strength Corson Alloy NKC1816
Also newly added to the lineup is the NKC1816 alloy for connector terminal use, which maintains the high strength while improving conductivity. Along with strength surpassing that of the C7025 alloy (0.2% offset yield strength: around 820 MPa), conductivity has been raised to 50% IACS, making it ideal for applications demanding high strength in addition to high conductivity.
The Company will continue timely development of products answering customer demands, while building up supply capability. These two newly released alloys will be on display at the 6th Highly-functional Metal Expo to be held December 4 to 6 (Wednesday to Friday) at Makuhari Messe (Makuhari, Chiba).
