Henan San Kuang Machinery Technology Co., Ltd., established in 2014 with a factory spanning 10,000-30,000 m² and a dedicated team of 51-100 employees, is your reliable partner in crusher wear parts. We are proud to present our Composite Crusher Bimetallic Hammer Casting with High Cr White Iron Hardness HRC63-66 — a high-performance solution engineered to maximize crushing efficiency and reduce downtime. Our bimetallic hammers combine the extreme wear resistance of high chromium white iron with the toughness of low alloy steel, delivering a product that outperforms traditional single-material hammers in composite crusher applications. With annual export value reaching US$2.5-5 million and products shipped to ports worldwide (Shanghai, Lianyungang, Qingdao, Tianjin), we serve markets across North America, Europe, Southeast Asia, Africa, and beyond.
Product Features & Benefits
- Bimetallic Structure: A metallurgically bonded interface between a high chromium white iron working layer (HRC63-66) and a ductile steel base. This ensures the hammer head maintains sharp cutting edges while the shank remains strong and impact-resistant, preventing breakage.
- Extended Service Life: The high Cr white iron offers hardness up to HRC66, providing 2-3 times longer wear life compared to traditional high manganese steel (Mn13) hammers. This drastically reduces replacement frequency and maintenance costs.
- Optimized for Composite Crushers: Specifically designed for use in composite crushers (also known as vertical shaft impact crushers or sand making machines), our bimetallic hammer delivers consistent crushing performance for limestone, basalt, granite, and other medium-hard to hard materials.
- Customizable Weight & Dimensions: We offer hammers from 5 kg to 500 kg in weight, with dimensions tailored to your crusher model. The casting process (sand or lost foam) ensures precise geometry and balanced weight distribution for smooth operation.
- Heat Treatment & Quality Control: Each hammer undergoes rigorous heat treatment (quenching and tempering) to achieve the desired hardness and toughness. Our factory is ISO9001 certified, with additional certifications including SA8000, OHSAS18001, and more.

Why Choose Our Bimetallic Hammer?
- Proven Reliability: Our factory holds multiple certifications including ISO9001, ISO14000, TL900, and SA8000, ensuring consistent quality and responsible manufacturing.
- Global Reach: With export ports in Shanghai, Lianyungang, Qingdao, and Tianjin, we deliver efficiently to customers in over 20 countries across North America, Europe, Asia, Africa, and Oceania.
- Technical Support: Our team of engineers can assist in selecting the right hammer design based on your crushing application and material abrasiveness. We offer free consultations and sample testing upon request.
- Cost-Effective: Although the upfront cost of bimetallic hammers is higher than standard manganese steel, the extended wear life of 2-3 times results in lower total cost per ton of crushed material.
- Eco-Friendly: The bimetallic casting process reduces material waste, and the longer lifespan means fewer replacements, lowering the environmental footprint.

Frequently Asked Questions (FAQ)
Q1: What is the difference between bimetallic hammer and traditional high manganese steel hammer?
A1: Bimetallic hammers have a hard working layer (High Cr White Iron, HRC63-66) bonded to a tough steel shank. Traditional manganese steel hammers work-harden under impact but have lower initial hardness (around HB200). Bimetallic hammers offer 2-3 times longer wear life in abrasive applications, reducing replacement costs.
Q2: Can the hammer be customized for my specific crusher model?
A2: Yes, we can customize the hammer weight, dimensions, and mounting hole positions according to your crusher drawings. Please provide your original hammer specifications or a sample for reverse engineering.
Q3: What is the typical delivery time?
A3: For standard sizes (up to 50 kg), delivery is usually 15-20 days after order confirmation. For larger or custom orders, it may take 25-35 days. We have a flexible production schedule and can expedite for urgent needs.
Q4: Do you provide quality certificates or material test reports?
A4: Yes, every batch of hammers is supplied with a material certificate, hardness test report, and chemical composition analysis. Our factory is ISO9001 certified and we follow strict QC procedures.
Q5: How should I choose the correct hammer hardness for my material?
A5: For highly abrasive materials (e.g., granite, basalt, river gravel), our HRC63-66 high Cr white iron is recommended. For lower abrasion or high impact applications, we can adjust the hardness and base material toughness. Contact our technical team for guidance.
Q6: What is the warranty period for your bimetallic hammer?
A6: We offer a 12-month warranty against manufacturing defects (cracks, delamination). Wear life is not covered by warranty as it depends on operating conditions, but we guarantee that the hardness meets the specified range of HRC63-66.
Q7: Can I get a sample before bulk order?
A7: Yes, we can produce 1-2 sample hammers for testing. Sample cost is negotiable and will be deducted from the first bulk order. Please contact us to discuss sample availability and shipping.
Q8: How do you package the hammers for export?
A8: Our standard packaging is steel pallets with steel straps and wooden crates for larger sizes. Each hammer is individually wrapped with protective foam to prevent damage during transit. Markings include part number, weight, and heat number.
