Porous 89/11 bronze filters: Characteristics

Porous 89/11 bronze filters

AMES offers its customers the ability to manufacture porous bronze filters and components with specific shapes. Each of these special applications requires a specific mould to obtain the desired geometry and pore size. The mould is designed and built entirely in AMES’ dedicated tooling workshop.
