Graphite Metallizing Corp product story

Graphite Metallizing has developed several bronze Graphalloy grades that do not contain lead.
These essentially lead-free formulations are used in bearings and bushings where the potential for lead contamination is unacceptable.
Applications include deep-well and potable water pumps and food-processing equipment such as ovens and conveyors.
Graphalloy no-lead bronze has been accepted by the Food and Drug Administration (FDA) as suitable for many food-grade applications.
The family of no-lead bronze offers all the advantages of leaded bronze Graphalloy without any sacrifice in performance, according to the company.
Graphalloy bushings and bearings are non-galling and are dimensionally stable, even when submerged, under load or experiencing wide temperature swings.
There are Graphalloy grades that can withstand temperatures ranging from cryogenic to +1,000F.
As Graphalloy bushings and bearings are self lubricating, they are suitable for applications where maintenance operations are infrequent or difficult.
