Comparison of CNC Machining Materials

CPVC (Chlorinated Polyvinyl Chloride) is a thermoplastic plastic obtained by chlorination modification of polyvinyl chloride (PVC). Such structural changes enable it to far outperform ordinary PVC in terms of heat resistance, mechanical properties, and chemical resistance, making it an ideal material for high-temperature and corrosive environments.

PEI (polyetherimide) is a high-performance thermoplastic engineering plastic that combines excellent heat resistance, mechanical properties, and chemical stability, enabling it to be widely used in high-end industrial fields such as aerospace, electronics and electrical engineering, and medical equipment.

Polyvinyl chloride (PVC) is a widely used thermoplastic polymer material characterized by excellent mechanical properties, outstanding corrosion resistance, and superior electrical insulation performance. By incorporating various additives, it can be tailored to meet customized requirements. Owing to its unique combination of properties, PVC finds extensive applications in fields such as construction, industry, packaging, and healthcare.

C101 copper, also known as HC copper (High Conductivity Copper) or more precisely, high-conductivity copper, has a nominal electrical conductivity of 100% IACS (International Annealed Copper Standard)—a benchmark level for conductive performance. It also features excellent high thermal conductivity, making it the preferred material for various electrical components (such as terminals) and conductors (such as power transmission busbars).
Furthermore, this material possesses high ductility (enabling easy complex forming processes like stretching and bending) and reliable impact resistance. While meeting the requirements for electrical performance, it can also accommodate the structural stability demands of mechanical processing and practical operating conditions, making it truly a high-quality copper material that combines multi-functional properties with practical value.
