At Sur/Fin 2018, Haviland Products Co. will feature its Havalloy ZN-TCP zinc-nickel alloy plating process, designed to provide ductile deposits and faster plate times on complex-shaped parts containing 13-15 percent nickel by weight.

Haviland Products Co. will feature its Havalloy ZN-TCP zinc-nickel alloy plating process, designed to provide ductile deposits and faster plate times on complex-shaped parts containing 13-15 percent nickel by weight. According to the company, the process allows for uniform deposition across a wide range of current densities, and can accept clear, iridescent and black (non-silver) chromate coatings.

Haviland says the process conforms to many automotive manufacturing specifications, including heat-aging requirements, and it recently eclipsed the required 12 cycles in the CETP 00.00-L-467 200903 cyclic salt spray/heat/humidity test without recordable mass loss. It also is said to routinely pass neutral salt spray testing to red rust after 1,000 hrs., often exceeding 2,000 hrs. before detectable red corrosion, and 800-1,000 hrs. to white corrosion. Protection can be further extended further with the company’s Prodigy nanotechnology sealer.
