NC Alloy By making improvements to the Corson alloy, it achieves extremely high mechanical strength without containing beryllium and excellent heat resistance that surpasses that of high beryllium copper. 

NC alloy is a newly developed material based on the Corson alloy as a beryllium copper substitute that does not contain beryllium, which is one of the specific first-class designated chemical substances. By combining the main additive elements Ni and Si in a well-balanced manner according to the purpose, the amount of Ni2Si is optimized, and precipitation strength is promoted by adding Cr and Sn, and it combines high heat resistance with excellent mechanical and physical properties.

NC50 

NC50 has the same performance as low beryllium copper alloys, and cold-worked drawn products meet the JIS Z3234 Class 3 standard. This product can be used for electrode materials, related jigs, and in all other situations. In particular, by using it for plunger tips for die casting machines, – Long life due to excellent wear resistance – Saving lubricants and improving the quality of die casting products – Improved productivity by shortening waiting time (cycle time) 

Main applications: 

Electrodes for resistance welding/Tip base/Gun arm/Plunger tip. NC alloy Practical examples of NC alloy Both materials can be used for plunger tips for die casting machines, but NC50 is particularly suitable. 

NC alloys also demonstrate their excellent performance as sliding parts for engines used under extremely harsh conditions other than plunger tips. 

Furthermore, due to its high hardness and excellent wear resistance, it is also used as a brake material for roller coasters, etc., and has a lifespan that is more than 10 times longer than conventional materials. 

In the field of resistance welding, it is used as an excellent electrode material for seam welding electrodes at steel companies, and in the field of mobile phones, it is also used for micro-welding electrodes for small parts such as crystal oscillators. 

Application to molds NC alloys have thermal conductivity that is more than three times superior to mold steels commonly used in molds, and is also superior to high-strength beryllium copper. By utilizing the high thermal conductivity of this NC alloy in resin molding molds, benefits are created by shortening the molding cycle. Compared to P-20 steel, the price difference of NC alloys is more than 10 times, but if molding is performed for more than 50,000 shots, it is possible to make up for the material cost, and considerable benefits can be expected for 100,000 shots.
