Metal Stamping & Sheet Metal Fabrication Material Capabilities
Selecting the right material grade determines the structural success and cost-efficiency of your components. Established in 1997, Kailai specializes in precision metal stamping and sheet metal fabrication, with carbon steel and standard mild steels serving as the core foundation of our high-volume production capabilities. We also process stainless steel and commercial aluminum to meet diverse engineering needs.
Our engineering team analyzes your technical drawings during the Design for Manufacturability (DFM) stage. We closely evaluate specific mechanical properties—such as tensile strength, yield strength, and material ductility—to ensure the selected metal stock can withstand deep drawing and progressive die stamping without fracturing or dimensional deviation.
Material You Can Choose
We convert your technical drawings into high-tolerance stamped parts using certified raw metal stocks, eliminating the risks of out-of-gauge variation or material failure. Every sheet and coil we process complies with strict industry standards, guaranteeing reliable component service life and zero blueprint deviation for your custom production runs.
Our materials are:
Materials
Core Materials
Low Carbon Steel
Low carbon steel is our most frequently processed material, driving the majority of our high-volume stamping production. This range offers exceptional cold formability, high material ductility, and superior weldability, striking the ideal balance between part reliability and production economy.
Core Material Grades: Q195 (AISI 1006 / 1008), Q235 (ASTM A36 / AISI 1015)
Stamping Thickness Range: 0.5 mm – 10.0 mm
Typical Applications: Industrial mounting brackets, appliance base plates, general connection hardware, non-structural automotive parts.
High-Strength Structural Steel
For heavy-duty components that require high load-bearing capacity and elevated tensile strength, we utilize our heavy-tonnage presses to stamp thick-gauge structural steel without fracturing or dimensional deviation.
Core Material Grades: Q345 / Q355 (ASTM A572 Grade 50)
Stamping Thickness Range: 1.5 mm – 12.0 mm
Typical Applications: Heavy machinery chassis, structural construction connectors, heavy-duty load brackets, automotive structural reinforcement plates.
Galvanized steel
Galvanized steel is our recommended choice when you need the structural strength of carbon steel but require cost-effective rust prevention without post-production plating. The protective zinc layer remains intact throughout our blanking and forming processes.
Core Material Types: SECC (Electro-Galvanized), SGCC (Hot-Dip Galvanized)
Stamping Thickness Range: 0.4 mm – 4.0 mm
Typical Applications: Outdoor electrical enclosure housings, HVAC duct brackets, internal appliance chassis.
Precision Stainless Steel Alloys
We regularly stamp and fabricate stainless steel for applications that demand high corrosion resistance or elevated-temperature durability. Our facility enforces strict material segregation during tool and die operations to eliminate iron contamination and protect final surface quality.
Corrosion-Resistant Grades (Austenitic): Stainless Steel 304 (SUS304 / 1.4301), Stainless Steel 316 / 316L (Marine & Medical Grade)
Heat-Resistant Grades (Ferritic): Stainless Steel 409 (SUH409L / 1.4512)
Stamping Thickness Range: 0.5 mm – 6.0 mm
Typical Applications: Food processing hardware, medical apparatus frames, marine-grade enclosures, automotive exhaust system mufflers and catalytic converter heat shields.
Aluminum & Aluminum Alloys
Aluminum is our primary material for lightweight components, housing enclosures, and parts requiring high thermal or electrical conductivity. It offers excellent formability and serves as an ideal base for post-production anodizing or powder coating.
Core Material Grades: Aluminum 5052 (High fatigue strength & marine durability), 6061-T6 (Structural grade), 3003 (General stamping & heat exchangers)
Stamping Thickness Range: 0.8 mm – 8.0 mm
Typical Applications: Weight-sensitive electronic chassis, lightweight automotive stampings, heat sinks, industrial protective guards.
Copper & Brass Alloys
Our facility offers precision cold-stamping for copper and brass alloys, focusing on electrical and thermal hardware. These materials provide outstanding electrical conductivity, high material ductility, and reliable chemical stability under precision tolerances.
Core Material Grades: Pure Copper (C11000 / T2), Brass (C26800 / H65), Beryllium Copper
Stamping Thickness Range: 0.3 mm – 3.0 mm
Typical Applications: Electrical terminals, power distribution busbars, switchgear components, grounding clips, electronic hardware.

Material Specification & Quality Assurance
To guarantee full compliance with international standards (including ASTM, DIN, JIS, and ISO), Kailai enforces a strict material verification workflow at our facility before production begins:
Mill Test Certificates (MTC): Full material chemical composition and mechanical property records are maintained and available for every batch of raw metal.{kailai-Raw-material-traceability-report.pdf}
Precision Gauge Verification: Incoming sheet metal and coils undergo physical thickness inspections to ensure they align perfectly with your technical drawing specifications.
Surface Integrity Inspection: Raw metal stock is pre-screened for rust, deep scratches, or rolling scale to protect final part aesthetics and prolong tool life.
