PEEK
Corrosion Resistance, Strength, Temperature Resistant
PEEK (Polyetheretherketone) is a top-performing thermoplastic engineering plastic, featuring excellent high-temperature resistance, robust mechanical properties, versatile corrosion resistance, top-tier biocompatibility, exceptional dimensional stability, and outstanding electrical insulation and radiation resistance. It is widely used in high-end fields such as aerospace, high-end medical care, and electronic semiconductors.
ABS
Strength, Economical, Processability
ABS (Acrylonitrile-Butadiene-Styrene Copolymer) is a well-balanced engineering plastic with good mechanical properties, excellent impact resistance, and easy processability. These characteristics have led to its widespread application in fields such as consumer electronics, household appliances, automotive industry, and daily necessities.
Steel Alloy 4140
Impact Resistance, Fatigue Resistant
AISI 4140 Alloy Steel is a medium-carbon chromium-molybdenum steel with a carbon content of about 0.38–0.43%. It offers an excellent combination of strength, toughness, wear resistance, and machinability. When heat-treated, it provides outstanding mechanical properties, making it widely used in gears, crankshafts, connecting rods, bolts, and critical components in the oil and gas industry.
