ตระกูลโลหะผสม

Steel alloyed with elements like chromium, molybdenum, or vanadium to enhance strength, hardness, or toughness beyond plain carbon steel.

High-carbon steel alloyed for hardness, abrasion resistance, and heat resistance, used to make cutting, shaping, and forming tools.

Copper combined with tin (bronze), zinc (brass), or other elements to improve corrosion resistance, conductivity, or machinability.

Nickel-based alloys known for exceptional heat and corrosion resistance, widely used in aerospace turbines and chemical processing.

Carbon-manganese steel produced in standard shapes (I-beam, angle, channel) for load-bearing construction and infrastructure applications.

Iron-carbon alloy where carbon content (0.05–2.1%) primarily determines hardness and tensile strength. The most widely produced steel type.

Medium-to-high carbon steel with high yield strength, allowing it to flex repeatedly under load and return to its original shape.

Iron-carbon alloy containing at least 10.5% chromium, which forms a passive oxide layer that resists corrosion and staining.

High-carbon, high-chromium steel engineered for extreme hardness, wear resistance, and fatigue life in rolling-element bearings.

Multi-principal element alloys with 5+ elements in near-equiatomic ratios.

Titanium combined with aluminum, vanadium, or other metals to achieve a high strength-to-weight ratio with excellent corrosion resistance.

Aluminum combined with copper, magnesium, silicon, or zinc to improve strength and machinability while retaining low density.
