The steel-based copper alloy products manufactured by IEM are created by bonding a layer of copper alloy material onto high-quality steel surfaces using high-tech processes. The specific copper alloy used can be selected from various existing grades based on customer requirements.

Key Characteristics:

1.Cost-Effective: Offers a significant cost advantage over solid copper products, reducing procurement costs while meeting client needs.

2.Dual-Alloy Performance: Combines the wear resistance of copper alloys with the high mechanical strength of steel.

3.Interchangeability: Fully interchangeable with standard copper alloy products in terms of model and fit.

4.Customizable Alloys: Can cast different grades of copper alloys based on working conditions (e.g., leaded copper alloys for low friction).

5.Self-Lubrication: Graphite plugs or patches can be embedded in the sliding surface to achieve self-lubrication.

6.Post-Processing: Supports further processing, such as heat treatment of the steel base and machining of the alloy layer.

7.Complex Geometry: Capable of casting single or multiple layers of copper alloy on different or complex surfaces as per design requirements.

8.High Load Capacity: Superior mechanical load-bearing performance compared to pure copper products, particularly in impact strength.

High Bonding Strength

The steel-based copper alloy products produced by our company feature extremely high bonding strength between the steel and copper layers. The bonding strength of Carbon Steel + High-Strength Brass composites can exceed 300 MPa.These materials are already widely used in complex working conditions, such as automotive stamping dies.

 IEM Dual-Alloy V-Guides & Drive Guides

The base material for IEMs dual-alloy V-guides and drive guides is low-carbon steel, while the working surface consists of high-strength Aluminum Bronze or High-Manganese Aluminum Bronze. Graphite is embedded in the lubrication surface.

1.Performance Boost: Compared to general copper alloy drive guides and V-guides, the welded copper layer improves performance by approximately 15% over cast copper products.

2.Cost Reduction: By replacing pure copper, material costs are significantly reduced, lowering overall usage costs.

3.Impact Resistance: The low-carbon steel base provides superior impact resistance, preventing cracking under heavy impact loads.

4.Durability: High hardness and excellent wear resistance prevent galling (seizing). These products are maintenance-free and offer a longer service life.

5.Operating Temp: Maximum operating temperature reaches 120°C, making them widely suitable for new energy vehicle (NEV) molds.

DANLY Dual-Alloy Bushings

DANLY dual-alloy bushings combine the high strength, high load capacity, and impact resistance of a steel base with the low friction coefficient and high wear resistance typical of copper bushings.

1.Superior Value: Their comprehensive performance exceeds that of solid copper bushings, offering excellent cost-effectiveness as a direct replacement.

2.Solving Specialized Challenges: These products solve issues where pure alloy copper bushings cannot be used. For example, in the mold industry, the outer surface requires hardening (quenching) to improve load capacity and impact resistance, while the inner bore requires a low friction coefficient to prevent seizing against the steel shaft during high-speed operation.

IEM Dual-Alloy Guide Plates

The copper alloy surface hardness of IEMs dual-alloy guide plates exceeds 210 HB, fully meeting the requirements of major customers for relative friction movements under high loads.

1.Best of Both Worlds: They possess the low friction and wear resistance of copper alloys, along with the high strength and impact resistance of steel, all at a competitive price point.

2.Vs. Traditional Sintered Plates: Traditional steel-copper sintered guide plates (made by rolling copper alloy powder onto steel) have low hardness and a porous alloy layer prone to peeling, making them suitable only for low-load, non-impact scenarios.

3.Denser Structure: In IEMs dual-alloy guide plates, the copper layer is thinner and free of pores, resulting in a denser metallographic structure and better wear resistance than solid copper alloys.

4.Better Base Material: The use of high-quality medium-carbon steel for the base provides a higher impact load ratio, delivering superior performance compared to sintered guide plates.
