Tungsten Carbide Strips Solution Case: Wear-resistant Components for Mining and Construction Industry

1. Severe Abrasion Challenges in Mining & Construction Equipment

Mining crushers, conveyor scrapers, trenching tools and road milling parts continuously rub against rock, sand, gravel and mineral ore. Ordinary steel wear plates wear down rapidly, requiring frequent replacement and causing costly machine downtime. Under high impact plus abrasive wear, material toughness and wear resistance are both critical.

Tungsten carbide flat strips are widely adopted as overlay wear inserts to extend the service life of heavy equipment components.

2. What Are Tungsten Carbide Flat Strips Used For

Carbide strips are rectangular solid blanks, commonly welded or brazed onto steel substrates. They serve as the working surface that directly contacts abrasive materials. Typical applications include scraper blades, crusher liner inserts, bucket teeth protectors, asphalt milling picks and agricultural tillage parts.

We supply standard straight strips and custom notched, chamfered or pre-ground strips according to customer welding drawings.

3. Mining Wear Strip Application Case & Test Data

One client manufactures conveyor belt scrapers for mineral processing plants. Their original wear parts were made of high manganese steel, which needed replacement every 7–10 days. We supplied YG11C carbide strips for brazing on the scraper edge.

After field validation, the client reduced their spare part purchasing frequency and maintenance labor cost significantly, and placed repeat bulk orders for carbide strips.

4. Grade Selection for Heavy Abrasion Conditions

• YG8 / YG8C: Fine-medium grain, high wear resistance, for low-impact sand and soil abrasion;
• YG11C: Balanced toughness and wear resistance, most popular for scraper and conveyor wear strips;
• YG15: Higher cobalt content, excellent impact resistance, for rock crushing and heavy impact scenarios;
• Ultra-coarse grain grades: Recommended for extreme impact mining environments to avoid cracking.

We can adjust grain size and cobalt percentage to match your specific abrasion and impact load.

5. Our Production & Supply Advantages for Carbide Strips

• Stable large batch sintering for carbide strips, consistent hardness and density;
• Available services: cutting, surface grinding, chamfering, hole drilling as drawings;
• Support small trial samples before bulk mining project orders;
• Strict inspection for warpage, cracks and dimension tolerance, reduce brazing failure rate.

6. Summary

Tungsten carbide strips are a proven wear solution for mining and construction heavy equipment. The scraper case shows huge improvement in service life compared with traditional steel wear parts. Our factory provides multiple carbide grades, standard sizes and custom processed carbide flat strips for brazing applications.
