Microphosphating, considered the evolution of traditional phosphating treatments, is able to produce a high-performance coating, applicable to various chemical conversion needs of metals.
Thanks to the cleaning by micro-sandblasting and a special phosphating bath developed in collaboration with our important customer, leader in the fastener sector in 1996 (Nitrites and Nickel free), pitting is practically absent or very reduced.
Metals subjected to zinc-calcium microphosphating treatment reveal a lower coefficient of friction than other phosphated surfaces and have a dense layer of micro-crystals, the result of the chemical conversion of fasteners with low-thickness treatments.
