Loads, stiffness, fatigue, wear, sealing, conductivity, temperature, fluids, fire, radiation, vacuum, life and safety consequence.
A comprehensive engineering reference, material selection and manufacturing process database covering metals, alloys, polymers, elastomers, adhesives, sealants, composites, ceramics, glasses, electronic materials, foams, surface engineering, heat treatment and other manufacturing processes. It provides typical engineering properties, metallurgy, process guidance, compatibility information, standards and selection tools to support design, manufacturing and quality professionals. All values are representative guidance and should be verified against the applicable specifications, certified material data and approved design allowables before use.
Loads, stiffness, fatigue, wear, sealing, conductivity, temperature, fluids, fire, radiation, vacuum, life and safety consequence.
Sheet, plate, bar, forging, casting, extrusion, powder, moulding compound, prepreg, adhesive film, seal compound or coating system.
Heat treatment, welding, brazing, bonding, moulding, curing, plating, anodising, painting, machining, NDT and cleanliness can change performance.
Typical handbook values are educational. Safety-critical design requires approved statistically based allowables and environmental knock-downs.
Check galvanic couples, chemical resistance, thermal expansion, seal fluids, adhesive surfaces, fire/smoke/toxicity and contamination.
Approved source, specification revision, certificate, traceability, inspection, process qualification, change control and retention.
Conceptual only. It shows why carbon content and thermal path affect ferrite, austenite, pearlite and cementite. Real heat treatment also depends on time, alloying, section size, cooling rate and prior microstructure.
Generally ductile with many slip systems. Examples: aluminium, copper, nickel and austenitic stainless steel.
Strength and low-temperature toughness can be strongly temperature/rate dependent. Examples: ferritic steel, chromium, tungsten.
Fewer easy slip systems at ambient temperature. Examples: magnesium, alpha titanium and zinc.
Use grade-specific diagrams to understand transformation during isothermal holding or continuous cooling. They are essential for hardenability, martensite formation and avoiding undesirable products.
Solution treat, quench and age to form strengthening precipitates. Over-ageing may improve corrosion or toughness while reducing peak strength.
Grain size, flow lines, crystallographic texture and test direction can dominate toughness, fatigue, formability and stress-corrosion performance.
Risk depends on electrolyte, area ratio, potential difference, coating damage, geometry and duration. Use an approved galvanic series for the actual environment.
Confirm each requirement before approving the material selection. Every item uses the same fixed-size control and remains fully selectable by clicking anywhere on its card.
