Technical Data
High performance copper alloy
NKT322
1. Introduction
Nikko Metal Manufacturing    developed a new original alloy, NKT322. NKT322 is a Fe bearing titanium copper modified by optimized manufacturing process. NKT322 highly improved strength and bend formability comparison with conventional titanium copper.
This technical brochure should help understand NKT322.
This data included are normal numbers.

6. Bend Formability
W shaped bending test was performed to evaluate minimum bend radius without surface crack (MBR). Table.4 shows MBR/t (Minimum Bend Radius /Thickness). Fig1 shows typical surface appearance. NKT322 has high strength and even better good bend formability.

7. Stress Relaxation Resistance
Stress relaxation resistance is highly important for maintaining the contact force for long period of time or at elevated temperatures. Fig.2 exhibits the stress relaxation resistance of NKT322. It has excellent stress relaxation resistance in comparison with beryllium copper.
