Additives and Master Alloys

MBN develops high-purity copper-manganese-phosphorus (Cu-Mn-P) alloys tailored for both brazing and sintering applications. These alloys are engineered for tunable melting points, thanks to precise control of phosphorus content together with eutectic CuMn, making them ideal for thermal processes where flow behavior and melting range are critical.

In brazing, Cu-Mn-P alloys offer excellent wettability, strong adhesion, and the potential for flux-free joining, especially with stainless steel, copper, and ferrous substrates. In sintering, these alloys can function as activating phases or infiltration agents, improving densification and mechanical bonding, particularly in automotive components such as valve seats, filters, and gear assemblies.

Manganese contributes strength and oxidation resistance, while phosphorus lowers melting point and enhances deoxidation during processing. The high purity of MBN powders ensures consistent performance, clean microstructures, and strong, reliable joints.

These alloys are well-suited for use in automotive sintered parts, and high-performance metal joining and HVAC parts.

MBN offers custom-engineered master alloys and ferroalloys, specifically developed for high-purity applications. These materials are based on elements such as manganese, molybdenum, and others, and are designed without carbon or sulfur contamination, making them ideal for critical sintering and alloying processes.

Unlike standard commercial ferroalloys, MBN’s materials can be produced with non-standard metal contents according to customer-specific requirements, allowing full flexibility in chemical composition and performance tuning for sensitive metallurgical environments.

An additional advantage is the finer particle size distribution achievable through MBN’s powder production technologies. This results in improved compressibility, better homogeneity, and enhanced sinterability, especially valuable in powder metallurgy for automotive, aerospace, and advanced tooling applications.

MBN supports customers with tailored compositions, narrow tolerances, and process-optimized powder characteristics to meet the most demanding technical standards.

MBN develops Copper-Chromium (Cu-Cr) master alloys designed as sintering aids in Copper or Iron based powder metallurgy systems. Produced via solid-state mechanical alloying, these materials ensure homogeneous distribution of chromium, enabling precise control over alloy behavior during sintering.

MBN’s powders offer flexible chromium content, which can be customized to customer-specific requirements. The solid-state nature of the mechanical alloying process eliminates segregation issues, producing a fully pre-alloyed, high-purity material with no unwanted phases or contamination.

The fine particle size and uniform composition improve compressibility, sinterability, and final part density, making these master alloys ideal for enhancing mechanical strength, conductivity, and oxidation resistance in sintered parts.

Applications include electrical contacts, structural components, and thermal management systems in sectors such as automotive, electronics, and industrial tooling.
