Shandong Sino New Material Co., Ltd. has been a trusted manufacturer of premium tinplate strips since 2018, specializing in thin-gauge materials for precision applications. Our 0.15mm thickness tinplate strip with 1.1/1.1 tin coating is specifically engineered for battery component manufacturing, offering excellent corrosion resistance, solderability, and dimensional stability. This product helps battery producers achieve reliable conductivity and long service life in terminals, connectors, and casing parts.
Every coil is produced under strict quality control, using advanced cold rolling and continuous annealing processes. The 1.1/1.1 tin coating ensures uniform protection on both sides, reducing oxidation during forming and assembly. With an annual export value of US$2.5-5 million and a factory spanning 10,000-30,000 square meters, we deliver consistent quality to demanding markets across North America, Europe, Asia, and beyond.
Key Features & Technical Specifications
- Ultrathin precision: 0.15mm thickness with tight tolerance (±0.005mm) enables lightweight battery designs without sacrificing strength.
- Balanced tin coating: 1.1 g/m² per side (total 2.2 g/m²) meets the balanced coating standard for electronic contacts.
- Excellent formability: Available in Tempers T1 to T5 for deep drawing, bending, or flattening operations.
- Surface options: Bright finish for aesthetic battery casings; matte finish for improved adhesion of insulating layers.
- Customizable width: From 10mm to 600mm slitting, with clean, burr-free edges.

Why This Tinplate Strip Suits Battery Manufacturing
Battery parts demand materials that resist electrolyte corrosion, provide stable electrical contact, and allow high-speed stamping. With an optimized tin layer, this strip prevents oxidation during storage and use, ensuring low contact resistance. The 0.15mm thickness reduces overall weight, supporting energy density goals in lithium-ion and alkaline batteries. Moreover, our ISO9000-certified production line (ISO9000:2000) guarantees batch-to-batch consistency, minimizing downtime during stamping or assembly.
Our team provides technical support for material selection—whether you need soft temper for deep-drawn battery cans or harder temper for terminals. We also offer customized slitting, edge finishing, and packaging (anti-rust paper + vacuum-sealed coils) to protect the strip during sea freight.
Trusted by markets worldwide: Shandong Sino New Material delivers to over 10 regions including Eastern Europe, Southeast Asia, South America, and North America. Our shipping ports (Qingdao, Tianjin, Shanghai) ensure fast and cost-effective logistics. With 101–200 skilled employees and a 30,000 m² factory, we can handle both small trial orders and large container volumes.

Frequently Asked Questions
-
Q: What is the tolerance on the 0.15mm thickness?
A: We maintain a thickness tolerance of ±0.005mm, which is suitable for high-precision stamping in battery components. -
Q: Can the tin coating be increased for more corrosion resistance?
A: Yes, we can produce with higher coating weights (e.g., 2.8/2.8 g/m²) upon request; 1.1/1.1 is our standard balance coating for electronic parts. -
Q: Is the strip available in coil or sheet form?
A: Standard supply is in coil form (ID 508 mm). We can also slit to narrow widths or cut lengths as per your order. -
Q: What hardiness/temper is recommended for battery can deep drawing?
A: For deep drawing, we suggest Temper T1 or T2 (soft). For terminal connectors, T3 or T4 provides better spring-back resistance. -
Q: Do you provide a passivation treatment to prevent tin oxidation?
A: Yes, we offer chemical passivation (chromate or trivalent) and oil coating to maintain surface quality during transport. -
Q: What is the minimum order quantity?
A: For standard specifications, MOQ is 1 ton per size. Customized widths may have higher MOQ; please inquire. -
Q: How do you ensure the tin coating is uniform on both sides?
A: We use continuous hot-dip timing lines with precise air knives to control coating weight, verified by X-ray gauge and wet chemical analysis.
