m4p™ CuNiSiCr
m4p™ CuNiSiCr is a high-performance copper-based material in powder form. It is characterized by its high electrical and thermal conductivity, combined with high hardness and strength. This exceptional level of strength for copper-based materials is achieved through thermal follow-up treatment (solution annealing followed by tempering).
The material is utilized in various areas of machine and mold construction, where the combination of strength and conductivity is crucial, such as in cooling inserts for molds and die casting machines. Additionally, it has numerous applications in electrical engineering and engine construction. The high seawater resistance of the material makes it suitable for construction parts or fixings in marine applications.
m4p™ Brz10
m4p™ Brz10 is an excellent engineering material known for its acceptable elongation and medium hardness. In addition to its good mechanical strength properties, this tin bronze is characterized by excellent corrosion resistance, particularly in seawater and mine effluents. This makes it ideal for applications in the valve industry, including pump housings, guide vanes, and impellers for pumps and turbines.
The material’s good mechanical properties are complemented by its excellent sliding properties, making it traditionally used in the manufacturing of plain bearings and helical gears. Due to its appealing color, m4p™ Brz10 is also used in jewelry and design applications.
m4p™ CuCrZr
m4p™ CuCrZr is a high-cost powder material ideally suited for high-performance applications in the aerospace industry and motorsports. To ensure high reliability, the powder is produced through a unique process that excludes the use of a crucible.
m4p™ CuCrZr is a hardenable copper alloy known for its high thermal and electrical conductivity, as well as its acceptable hardness even at elevated temperatures.
m4p™ PureCu
m4p™ PureCu is a high-grade copper metal powder known for its excellent electrical and thermal conductivity, which is theoretically only surpassed by elemental copper or silver. Due to these properties, processing m4p™ PureCu in the Powder Bed Fusion (PBF) process is recommended only with suitable sintering and melting plants and special parameter sets to achieve low component porosities.
Components made from m4p™ PureCu also exhibit high ductility and corrosion resistance to aqueous solutions and non-oxidizing acids. However, the suitability for use or post-treatment in reducing atmospheres (e.g., annealing in a hydrogenous atmosphere) needs to be tested on a case-by-case basis.
The primary applications for m4p™ PureCu are found in electrical engineering and electronics, as well as in heat-dissipating components.
m4p™ Al-Brz8,5
m4p™ Al-Brz8.5 is a copper-based metal powder, alloyed primarily with aluminum, nickel, and iron, making it suitable for additive manufacturing. This aluminum bronze is noted for its antifriction properties and enhanced resistance to abrasive and erosive wear stress. Among copper materials, m4p™ Al-Brz8.5 stands out for its particularly high mechanical strength and toughness, which are maintained even at low temperatures.
Additionally, its corrosion and cavitation resistance make it ideal for applications in the maritime sector.
m4p™ CuZn42
m4p™ CuZn42 is a brass alloy with high zinc content, known for its good mechanical properties and excellent workability. Due to its low lead content, this material is suitable for jewelry and drinking water applications, though compliance with national and local regulations is necessary. In certain areas, only partial surfaces of equipment and parts in sensitive contact are permitted.
The machined surfaces of m4p™ CuZn42 exhibit the characteristic gold-colored appearance of brass alloys. Its corrosion resistance and formability are excellent. However, powder production and processing for additive manufacturing can be challenging due to brass’s inherent properties. To address this, m4p™ CuZn42 has been given a special surface modification to improve its additive processing behavior, enabling relative densities greater than 99.5%.
