Covering 7 Major Categories and Over 30 Metals, Serving 20+ Industries with One-Stop Precision Parts Solutions
Shanghai Jinxi, a professional factory with over 20 years of experience in precision CNC machining, firmly believes that high-quality parts stem from a deep understanding and precise control of materials. From ordinary carbon steel to aerospace-grade titanium alloys, from general-purpose aluminum alloys to corrosion-resistant special alloys, we have established a comprehensive processing system covering 7 major categories and over 30 commonly used metals. We can provide one-stop solutions for over 20 industries, including automotive, aerospace, medical devices, and mold manufacturing, from raw material selection and process optimization to finished product delivery.
I. High-Quality Carbon Structural Steel: The Cornerstone of Industrial Manufacturing
As the most widely used basic material in machinery manufacturing, our core processing includes low-carbon steel 20, medium-carbon steel 45 (most commonly used), and high-carbon steel T10. Low-carbon steel exhibits excellent plasticity and weldability, and can be hardened by carburizing; medium-carbon steel offers a balanced strength and toughness, with significantly improved performance after tempering; high-carbon steel achieves high hardness and good wear resistance after quenching. Typical products include 45 steel shafts and gears, 20 steel pins and welded parts, and T10 steel cutting tools and measuring instruments, widely used in general machinery, automotive, and construction machinery industries.
II. Alloy Structural Steel: The Backbone of Heavy-Duty Applications
Adding alloying elements to carbon steel significantly enhances its strength, toughness, and fatigue resistance, making it the preferred choice for critical heavy-duty structural components. Core processing grades include 40Cr, 42CrMo, and 65Mn, which feature good hardenability, high-temperature strength, and long service life. It can manufacture automotive half-shafts, heavy machinery spindles, wind turbine gears, springs, and other components, serving the automotive, construction machinery, wind power, and mining industries.
III. Stainless Steel: Guardians of Corrosion-Resistant Environments
We possess the capability to process a full range of austenitic, martensitic, and ferritic stainless steels, with core grades 304 (most commonly used), 316L, and 440C. 304/316L offer excellent corrosion resistance and weldability, while 316L exhibits stronger resistance to intergranular corrosion. 440C achieves a hardness of HRC55-60 after quenching. Typical products include food machinery parts, chemical equipment, and surgical instruments, applied in food, medical, marine engineering, and environmental protection fields.
IV. Aluminum Alloy: The Preferred Choice for Lightweight Manufacturing
Low density and high specific strength make it a core material for lightweight manufacturing, solving problems such as processing deformation and tool sticking. Core processing grades include 6061-T6 (most commonly used), 7075-T6, and ADC12. 6061 has good machinability and can be anodized, 7075 has strength approaching that of steel, and ADC12 is suitable for precision machining after die casting. We can produce electronic casings, aerospace structural components, motor housings, etc., serving the electronics, aerospace, and new energy industries.
V. Copper and Copper Alloys: Experts in the Electrical Field
Possessing excellent electrical and thermal conductivity and wear resistance, copper is an irreplaceable material in the electrical industry. Core processing materials include T2 copper, H62 brass, and QBe2 beryllium bronze. Copper offers excellent electrical and thermal conductivity, brass has good machinability, and beryllium bronze boasts outstanding elasticity and wear resistance. It can be used to manufacture busbars, valves, spring contacts, etc., for applications in the electrical, electronic, power, and refrigeration industries.
VI. Titanium and Titanium Alloys: High-End Manufacturing Materials
With a density only 60% that of steel, it boasts the highest specific strength among metals, and exhibits extremely strong corrosion resistance and good biocompatibility. Equipped with specialized processing equipment, core processing materials include TC4 (most commonly used) and TA2. It can produce aero-engine blades, orthopedic implants, chemical heat exchangers, etc., serving high-end fields such as aerospace, medical devices, and marine engineering.
VII. Special Alloys: Solutions for Extreme Working Conditions
For extreme working conditions such as high temperature, high pressure, and strong corrosion, various special alloys can be processed. Our core grades include high-temperature alloy GH4169, corrosion-resistant alloy Hastelloy C276, and mold steel S136. We manufacture gas turbine blades, chemical reactors, precision molds, and more, serving industries such as aerospace, petrochemicals, and semiconductor equipment.
Our core material processing advantages include: 1) end-to-end quality control, with each batch of raw materials undergoing spectral analysis and material verification to ensure 100% compliance; 2) customized processes, tailoring cutting parameters for different materials to overcome the challenges of machining difficult materials; 3) our own heat treatment workshop, providing a full range of services including tempering, quenching, and carburizing; and 4) one-stop surface treatment, encompassing anodizing, electroplating, and polishing, enabling finished product delivery.
