Brass Strip – Process & Quality Assurance Statement
Our brass strips are produced to meet the needs of industries requiring reliable material for forming, conducting, and aesthetic applications, with tight control over composition and temper for repeatable performance.
Key process features
The manufacturing process combines modern rolling technology with precise annealing for optimal grain structure:
●Continuous Casting: High-quality cathodes and returns are melted and cast into slabs with controlled cooling to minimize segregation.
●Hot Rolling: Slabs are heated and rolled to intermediate thickness, breaking down the cast structure.
●Cold Rolling: Multiple passes reduce thickness to final gauge, improving surface finish and mechanical properties.
●Annealing: Intermediate and final annealing in protective atmosphere restores ductility and achieves desired temper (e.g., H02, H04).
●Slitting & Leveling: Coils are precision slit to width and leveled for flatness.
●Surface Treatment: Optional cleaning, polishing, or coating applied based on requirements.
●Coiling & Packaging: Strips are coiled or cut to length, then securely packaged to prevent damage during international shipping.
Quality control system
● Full traceability from cathode input to finished coil
● Material test certificates provided with every shipment
● Sample retention ≥3 years for third-party verification (SGS, BV, TÜV, etc.)
● 100% inspection of essential parameters:
• Chemical composition (optical emission spectrometry)
• Mechanical properties (tensile, elongation, and hardness testing on samples)
• Dimensional accuracy (micrometers and laser gauges; typical thickness tolerance ±0.005mm)
• Surface quality and flatness (visual + camber measurement)
• Coil weight and ID/OD consistency
● Internal standards exceed ASTM B36 requirements. Typical C26000 properties: Tensile strength 300-500 MPa (depending on temper), Excellent deep drawability, Reliable performance in forming and electrical applications.
● ISO 9001:2015 certified production ensures every brass strip delivers the consistency, workability, and quality your projects demand.
