Metaalsoorten

Metaalsoorten is a term used in some Dutch-language metallurgical literature to denote groups of metal alloys defined by composition, processing history, and intended properties. The concept helps organize alloys by base metal families (such as iron, aluminum, copper, nickel, and titanium) and by key alloying elements and treatment routes. In practice, metaalsoorten encompass familiar classes such as steel alloys, aluminum alloys, copper alloys, nickel-based superalloys, and titanium alloys, as well as subgroups like stainless steels, high-strength aluminum alloys, bronze, and brass. The term emphasizes both composition and performance targets, for example strength, hardness, creep resistance, or corrosion resistance.

Production and processing: Metaalsoorten are produced by melting base metals and alloying elements, followed by casting or forming, and often subjected to heat treatment to achieve desired microstructures. Common processing routes include annealing, quenching and tempering, solution heat treatment, aging (precipitation hardening), forging, and extrusion. Homogenization and quality control ensure consistent properties across batches.

Properties and applications: Depending on composition and heat treatment, metaalsoorten can offer a range of properties from high strength and stiffness to good corrosion resistance or thermal stability. They find use in construction, machinery, aerospace, automotive, electronics, and medical devices.

Standards and evaluation: Classification by metaalsoorten is supported by national and international standards organizations, such as ISO and ASTM, which define alloy names, composition limits, and testing methods. Typical evaluation includes hardness testing, tensile testing, impact resistance, and corrosion testing in relevant environments.

Research and trends: Ongoing work in metaalsoorten focuses on lightweighting, high-temperature performance, wear resistance, and sustainability, including alloy design, recycling of scrap, and additive manufacturing techniques that enable complex microstructures.
