Explore Specifications →Uzbekistan's industrial sector is undergoing a rapid modern transformation. High-throughput operations, such as the major mining activities at the Navoiy Mining and Metallurgical Combine (NMMC) and the Almalyk Mining and Metallurgical Combine (AMMC), are pushing machinery to its limits. Excavators, chutes, steel sintering mills, and crushing systems process millions of tons of abrasive gold, copper, and iron ore daily. In such conditions, standard structural steel components wear out rapidly, leading to frequent downtime and substantial maintenance costs.
As a leading supplier of premium hardfacing consumables and wear-resistant machinery, we provide specialized solutions engineered specifically to address these challenges. By incorporating advanced flux-cored welding wires and bimetallic chromium carbide overlay (CCO) wear plates into maintenance cycles, local operators can extend component service life by up to 300% to 500% compared to standard steel alloys.
Heavy machinery in Uzbekistan faces severe wear mechanisms, primarily high-stress grinding abrasion and moderate-to-severe impact. In open-pit mines across the Kyzylkum desert, silica sand and hard rock minerals aggravate surface degradation. Standard solutions like manganese steel often fail to work-harden efficiently under low-to-moderate impact conditions, resulting in rapid material loss.
Our Chromium Carbide Overlay (CCO) plates and high-chromium flux-cored wires (like our RX®wp series) introduce a dense distribution of primary M7C3 hexagonal chromium carbides within a tough eutectic matrix. This microstructure provides high bulk hardness (ranging from 58 to 62 HRC) while maintaining the structural resilience necessary to handle mechanical stress and shock loads.

How we protect heavy-duty assets in metallurgy, mining, cement, and power generation from premature failure.
Continuous throughput in cement operations demands reliable equipment wear performance. Our custom bimetallic liners protect key machinery like hopper chutes, raw meal cyclones, and clinker transfer chutes, ensuring consistent uptime.
Open-pit and underground extractions expose machinery to extreme abrasive wear. We supply cost-effective wear protection options for excavator buckets, heavy dragline liners, hopper linings, and crusher plates.
Steel production involves demanding operational conditions, including mineral friction, thermal stress, and chemical corrosion. Our wear plates and hardfacing wires are built to withstand high temperatures and impact loads.
We supply high-temperature hardfacing wires and custom liners for fan blade structures, conveyor chutes, pulverizer grinding segments, and dust collector hoppers in coal-fired power stations.
High-capacity bulk transshipment terminals require durable equipment. Our overlay plates extend the operating life of grab buckets, hopper liners, stacker-reclaimer components, and bulk transfer pipes.
For operations with minimal mechanical impact but severe sliding erosion, we fabricate wear-resistant, high-purity alumina ceramics designed to withstand highly abrasive slurry transport.
Collaborating with leading academic researchers and global industrial associations to stay at the forefront of wear science.
In 2023, leaders and materials scientists from Tangshan University—including Dean Yuan Shaoqiang, Vice Dean Li Jing, and Professor Yang Yuehui (Lead Researcher in Metal Materials and Forming Technology)—visited our manufacturing plant.
This collaboration focuses on optimizing carbide refinement techniques for hypereutectic alloys, ensuring that our flux-cored wires maintain high toughness and microstructural consistency for heavy industrial use.

See more products >A key factor in selecting hardfacing materials is understanding the relationship between the alloy chemistry and the operating environment. Standard solid welding wires rely heavily on external shielding gas (such as Argon/CO2 mixes) to protect the weld pool from nitrogen and oxygen contamination. In field repair applications, like those found in open-pit mining, wind can disrupt gas shielding, leading to weld porosity and reduced structural integrity.
Our self-shielded flux-cored welding wires contain internal gas-forming elements and deoxidizers within the core formulation. This allows operators to perform open-arc welding in demanding outdoor conditions without needing external gas cylinders, ensuring reliable deposition and consistent performance.

We ensure consistent quality across our product lines by sourcing raw materials through strict supplier vetting and conducting metallurgical testing on each batch. Each production run of flux-cored wire undergoes spectral analysis to verify alloy ratios and test-welding to assess arc stability, slag release, and deposition efficiency. This technical oversight ensures that our products meet the high standards required by industrial maintenance teams in Uzbekistan.

Flux-cored wire allows for the inclusion of alloy powders (such as chromium, carbon, boron, and niobium) inside the metal sheath, enabling the creation of specialized, high-alloy chemistries that cannot be drawn into solid wire. Additionally, self-shielded flux-cored wire eliminates the need for gas shielding, making it suitable for field repairs in windy outdoor environments.
