We not only possess advanced rolling and annealing technologies, offering a full range of high-quality products, including carbon steel strip, stainless steel strip, copper alloy strip, and aluminum alloy strip, but also specialize in cutting-edge material solutions such as specialty metal strip and nickel-based alloys. This authoritative purchasing guide provides an in-depth analysis of the performance characteristics of different materials, the stringent tolerances, and strategies for selecting high-precision metal strip to ensure project success.
What is Metal Strip?
Metal strip refers to a continuous strip of metal material formed by rolling, slitting, or precision processing. It features high precision, uniform dimensions, and a smooth surface. Common specifications:
Width: 10 mm–600 mm
Thickness: 0.02 mm–6 mm
Based on the processing technology, metal strips can be categorized as follows:
Hot-rolled strip: Has a slightly rough surface and average dimensional accuracy, suitable for structural parts and large components.
Cold-rolled strip: Has a smooth surface and high dimensional accuracy, suitable for precision processing and decorative purposes.

High Carbon Steel (e.g., 65Mn/SK5): Achieves high hardness and excellent elasticity after heat treatment, making it the top choice for manufacturing high-strength springs.
Huaxiao Advantage: Strict control over strip shape (flatness) after rolling, and providing precision strips with specified surface finishes and edge treatments (chamfered/round edges).
Corrosion Resistance and Ductility: Comprehensive Coverage of Stainless Steel Strip
Application Areas: Medical devices, precision electronics, home appliances, chemical equipment, and springs.
Austenitic Series (300 Series): The general-purpose champion of Stainless Steel Strip. Grades like 304/316L possess exceptional corrosion resistance and workability. We supply both low-carbon L-grade and high-strength H-grade.
Ferritic Series (400 Series): Offers a combination of magnetic properties and corrosion resistance, suitable for automotive exhaust systems and certain electronic components.
Martensitic and Precipitation-Hardening Steels: Such as 420/630, used for high-precision springs and structural parts requiring high hardness, high strength, and good heat resistance.
High Conductivity and High Elasticity: Precision Applications of Copper Alloy Strip
Application Areas: Electronic connectors, lead frames, heat sinks, and new energy battery connectors.
Electrical Copper (Oxygen-Free Copper): Highest electrical and thermal conductivity, suitable for power transmission and thermal dissipation applications.
Brass/Phosphor Bronze: Excellent elasticity, fatigue resistance, and electrical conductivity, commonly chosen for standard connectors and switches.
Beryllium Copper (BeCu) and Titanium Copper (TiCu): Rare alloys that combine ultra-high strength, elasticity, and conductivity, essential for high-end, high-insertion-cycle precision electronic connectors.
Lightweighting and High Formability: Aluminum Alloy Strip
Application Areas: Lithium battery casings, automotive lightweight structural components, radiators, and car body materials.
1000 Series (Pure Aluminum): Excellent thermal conductivity and corrosion resistance, used for electrolytic capacitors and heat sinks.
3000/5000 Series: Good strength and formability, crucial for lightweight structural components in the automotive and battery industries.

Corrosion-Resistant Alloys: Provide exceptional corrosion resistance in harsh environments such as strong acids and bases.
Precision Alloys: Include iron-nickel alloys, glass-sealed alloys, and precision resistor alloys for specialized electronic packaging and sensor components.
Other Specialty Metal Strip
Pure Nickel: Widely used in battery current collectors and electroplating, requiring extremely high purity and weldability.
Titanium Strip: Extremely light, high-strength, and corrosion-resistant, it is an important material for medical implants and aerospace.
The Core Determinants of "High Precision": Material Tolerances and Surface Treatment Standards
“High Precision” isn’t just a vague adjective; it’s a quantified technical indicator. Huaxiao Metal rigorously controls the following key parameters:
Strict Dimensional Tolerance Control
Thickness Tolerance: This is the core standard for high-precision metal strip. Our products offer tolerances of ±0.005mm or even tighter, far exceeding industry standards, ensuring consistency during high-speed stamping.
Width Tolerance: For narrow strips after slitting, we utilize high-precision cutting tools and tension control to minimize width errors.
Perfect Shape and Surface Quality
Straightness: Utilizing an advanced twenty-high rolling mill and tension leveling process, we ensure exceptional strip straightness in a stress-free state, eliminating defects such as wavy edges and bends.
Surface Roughness (Ra): Surface roughness can be customized based on customer requirements, ranging from bright annealed to matte, to meet subsequent coating, etching, or welding requirements.
