Brass balls are distinguished by their strong mechanical performance, excellent corrosion resistance and outstanding electrical properties. These balls are ideal for low friction systems and are available in a state of passivity. As an experienced supplier, Marteau- Lemarie offers a stock available in France for fast deliveries.

Corrosion resistance of brass ball
Good corrosion resistance in drinking water, brackish, marine (except under strong current conditions), in saline atmospheres, gasoline and its derivatives, alcohols. Resistant less effectively in the presence of acids and d Do not resist contact with hydroxides, cyanides, oxidizing acids. Corrosion resistance generally decreases with increased zinc content.
