Aluminum Bronze Components, Machined for Demanding Service
PartsMake specialises in high-performance C95400 and C63000 Aluminum Bronze machining. From material procurement to finished, site-ready components, we support critical seawater and sour-gas applications across the Middle East.
Our machining approach is tailored to the alloy’s metallurgical properties, helping valve seats, bushings and wear components meet precise geometric requirements with less need for on-site adjustment.

Surface finish capability
Built around the application
High-precision turning and milling for large-diameter seawater valve liners, heavy lifting friction discs and propeller shaft bearing bushings.
Material advantages
Designed for Gulf water and heavy loads
High salinity and warm seawater put materials under sustained pressure. Aluminum Bronze offers a strong combination of wear performance, corrosion resistance and dependable sliding behaviour for demanding service.
01 / Marine exposure
Natural resistance to marine fouling
The copper-based composition naturally resists marine organism attachment, helping maintain flow efficiency in desalination intake systems.
02 / Load capacity
Strength with useful ductility
Grades such as C95400 provide strength comparable to medium-carbon steel while retaining superior ductility.
03 / Sliding contact
Resistance to galling
Compared with stainless steel, Aluminum Bronze resists metal-to-metal seizure under high pressure—an advantage for sliding parts and heavy-duty valve trims.
C95400 and C63000
Machining control from stock to finished fit
Specialised tooling geometries and feed rates are selected to suit Aluminum Bronze hardness and thermal conductivity. This helps minimise internal stress and produce components that fit on site without secondary adjustment.
Precision turning and milling
For close-fitting bearing interfaces, hydraulic seals, valve components and rotating assemblies where geometry and surface quality matter.
Component specifications
