TECH BRIEFS AMETEK’ SPECIALTY METAL PRODUCTS WALLINGFORD Advantages AMETEK High Purity Nickel offers advantages to the rechargeable battery industry. Typical applications for rechargeable batteries include computers, cellular phones, power tools, electric vehicles, and camcorders. Other advantages offer: • Lowest electrical resistivity available in pure nickel strip. • Significantly low levels of surface oxides reduce die wear • Homogeneity, microcleanliness, and close composition control and provide excellent solderability. enhances weldability. • Excellent formability.
