Centrifugal Casting Alloy Powders for Engine Cylinder Liners, Bushings, Sleeves & Wear-Resistant Industrial Components
Product Overview
Iron-Based, Nickel-Based, Nickel-Tungsten Carbide and Cobalt-Based Alloy Powders for Centrifugal Casting, Bore Surface Hardfacing and Wear-Resistant Metallurgical Coatings
GREENSTONE Centrifugal Casting Alloy Powders are specialized metallurgical powders developed for the manufacture and surface reinforcement of engine cylinder liners, cylinder sleeves, bushings, bearing sleeves and other cylindrical components requiring high wear resistance and long service life.
The product portfolio includes iron-based (Fe-based), nickel-based (Ni-based), nickel-tungsten carbide (Ni-WC) and cobalt-based (Co-based) alloy systems, providing a broad range of hardness, wear resistance, corrosion resistance, high-temperature stability and metallurgical performance.
During centrifugal casting, rotational force distributes the molten or semi-molten alloy material along the internal cylindrical surface, enabling the formation of a functional wear-resistant layer. Properly selected alloy powders can be used to improve the bore surface hardness, abrasion resistance, scuffing resistance and service durability of components operating under demanding friction and thermal conditions.
GREENSTONE centrifugal casting powders are suitable for applications in the automotive, diesel engine, marine engine, heavy machinery, agricultural machinery, mining, power generation, oil & gas and industrial remanufacturing industries.
Powder chemistry and particle-size distribution can be customized according to the base material, centrifugal casting process, required hardness, operating temperature and wear mechanism.
Fe-Based Centrifugal Casting Alloy Powder
Iron-based alloy powders provide a cost-effective solution for producing hard, wear-resistant internal surfaces on ferrous components.
The Fe-Cr-C-Ni-Si alloy systems shown in this product family cover approximately 58–62 HRC, depending on composition and processing conditions. Chromium and carbon contribute to hardness and carbide formation, while nickel can improve toughness and metallurgical performance.
Typical applications include engine cylinder liners, cylinder sleeves, bushings, wear sleeves and internal bore surfaces requiring high hardness and abrasion resistance.
Ni-Based Centrifugal Casting Alloy Powder
Nickel-based centrifugal casting powders provide a combination of wear resistance, corrosion resistance, metallurgical compatibility and elevated-temperature performance.
Depending on alloy composition, the available Ni-Cr-Si-B / Ni-Cr-Co-Mo-W systems cover approximately 45–63 HRC. These alloys can be selected where iron-based materials cannot provide sufficient corrosion, thermal or tribological performance.
Typical applications include high-performance cylinder liners, industrial sleeves, bushings, internal wear surfaces and severe-service rotating machinery components.
Ni-WC Centrifugal Casting Composite Powder
Nickel-tungsten carbide composite systems are designed for particularly severe abrasive and erosive environments.
The nickel-based metallic matrix provides metallurgical bonding and toughness, while WC (tungsten carbide) provides extremely hard wear-resistant reinforcement. Different carbide contents can be selected to balance wear resistance, toughness and processability.
These powders are particularly suitable for heavy-duty cylinder liners, mining machinery, oilfield components, wear sleeves and industrial components exposed to abrasive particles or severe sliding wear.
Co-Based Centrifugal Casting Alloy Powder
Cobalt-based alloy powders are designed for applications requiring wear resistance, hot hardness, corrosion resistance and stability at elevated temperatures.
Co-Cr-Mo and related cobalt alloy systems are suitable for high-value components subjected to combinations of heat, friction, corrosion and mechanical wear.
Typical applications include high-temperature sleeves, valve-related components, engine components and severe-service industrial wear parts.
Main Advantages
High Internal-Bore Wear Resistance
Optimized alloy systems improve resistance to sliding wear, abrasion and scuffing on cylindrical working surfaces.
High Hardness Range
Selected formulations provide deposited hardness up to approximately 63 HRC, depending on alloy chemistry and processing conditions.
Multiple Alloy Systems
Fe-based, Ni-based, Ni-WC composite and Co-based materials allow powder selection according to cost, substrate, temperature, corrosion and wear requirements.
Excellent Metallurgical Integration
Proper centrifugal casting processing enables the functional alloy layer to metallurgically integrate with compatible substrate materials.
Suitable for Cylinder Liners and Sleeves
The powder systems are particularly suitable for internal cylindrical surfaces where uniform circumferential functional layers are required.
High-Temperature and Corrosion Options
Nickel- and cobalt-based compositions provide solutions for applications where conventional iron-based hardfacing alloys are insufficient.
WC-Reinforced Heavy-Duty Protection
Ni-WC composite powders provide significantly enhanced abrasion resistance for severe industrial operating conditions.
Controlled Particle Size
Powder particle-size distributions can be adjusted according to centrifugal casting equipment, component dimensions and metallurgical process requirements.
Custom Alloy Development
GREENSTONE can optimize alloy chemistry, hardness and particle-size distribution according to the customer’s substrate material, working conditions and target service life.
