special machining

In compliance with the new directives regarding the respect for the environment, in vigor in many countries worldwide and related to the reduction of CO₂ emissions in the atmosphere, Officina Meccanica Grisi has specialized in the processing of bars composed by the “K65” alloy produced by Wieland, with which we have established a strong supply relationship.

K65 is a special alloy of copper and steel which offers a high mechanical strength and is suitable for use at 120 bar pressure with relatively thin thicknesses. Consequently, the reduced weight of the pipes made by K65 alloy allows remarkable savings of material and reduction in costs.

The K65 tube fittings find their main application in the refrigeration, especially for large systems.
