Product Overview
Centrifugal Cast Aluminum Bronze Parts are high-strength wear-resistant rotary cast components mainly including aluminum bronze bushings, sleeves, bearing liners and wear rings.
Our aluminum bronze castings feature dense pore-free structure, ultra-high wear & seawater corrosion resistance, ideal for heavy-load marine, mining, wind power and petrochemical harsh working conditions.
Core highlights:
- Zero shrinkage porosity
- High roundness precision
- Custom size & alloy
- Long service life under heavy load

Key Features
Centrifugal force exhausts air during molten bronze solidification, drastically reducing porosity & shrinkage defects compared with sand casting, avoiding early bearing failure.
Centrifugal solidification forms uniform tiny grains, lifting tensile strength, hardness and wear resistance by 20%-40% to extend service life in heavy load equipment.
Rotary centrifugal forming guarantees high coaxiality, cylindricity and roundness; less machining allowance saves your raw material & processing cost.
Aluminum bronze alloy resists seawater erosion, cavitation and chemical corrosion, perfectly fit long-term marine offshore working conditions.
Long-life metal centrifugal molds support automated continuous casting, stable cycle and lower unit cost for bulk orders.
6. Oxidation & Hydrogen Absorption Control
Fast metal filling speed of centrifugal casting effectively solves aluminum bronze oxidation & hydrogen absorption issues, improving finished casting yield.
Packaging & Shipping
Professional Anti-Damage Packaging for Aluminum Bronze Castings
- Pre-treatment: Full degreasing, derusting and anti-rust coating for all casting surfaces; inner bores & threaded holes individually sealed with protective foam
- Inner cushioning: Pearl cotton wrapping for small bushings; soft foam filling inside liners, cardboard corner guards for both ends
- Separation & fixing: Partition plates inside boxes to avoid collision between workpieces, gap filling to prevent shifting
- Outer export package: Waterproof membrane lined fumigation-free wooden crates, tightly bound with packing belts
- Cargo Label Marking: Standard shipping cargo labels with product info, order No., weight & dimension are firmly pasted on each fumigation-free wooden crate for easy customs clearance & cargo identification
FAQ
Q: Can you customize the inner & outer diameter of aluminum bronze bushings?
A: Yes, we support fully customized OD, ID, wall thickness and length from 20mm to 1200mm ID.
Q: What's the advantage of centrifugal casting over sand casting for bronze bushings?
A: Centrifugal castings have far fewer pores & shrinkage, finer grain, higher roundness and lower machining cost.
Q: Are your aluminum bronze castings suitable for seawater marine equipment?
A: It depends on the material grade. For seawater marine equipment, we highly recommend C95800 marine aluminum bronze series, which features outstanding seawater & cavitation corrosion resistance for ship & offshore parts.
Q: Will large thin-wall aluminum bronze bushings deform during shipment?
A: Large thin-wall aluminum bronze bushings are prone to oval deformation if packaged improperly. Besides full multi-layer protective cushioning, we adopt standardized placement methods: we arrange the bushings to bear radial force instead of axial force, effectively preventing out-of-round distortion during long-distance sea and land transportation.
Q: What's your standard production lead time?
A: Mold making: 3-4 weeks Sample making: 1–2 weeks Mass bulk order: 3–5 weeks based on quantity.
