Shandong Sino New Material Co., Ltd., a professional manufacturer established in 2018 with a factory size of 10,000–30,000 square meters and an annual export value of US$2.5–5 million, proudly presents our Tinplate Sheet 0.15mm Thickness T1 Temper 1.1/1.1g/m² Tin Coating 950mm Width. This product is specifically engineered for the production of dry battery cases, offering superior corrosion resistance, excellent formability, and consistent thickness control. With our ISO9000 and ISO19011:2000 certified manufacturing processes, we ensure every sheet meets the stringent requirements of the battery industry, providing a reliable foundation for your battery casing needs.
Our tinplate sheets are manufactured using high-quality low-carbon steel coils and electrolytic tin coating technology. The precise 0.15mm thickness and T1 temper grade deliver an optimal balance of strength and ductility, making them ideal for deep drawing and stamping operations required for dry battery cases. The 1.1/1.1 g/m² tin coating on both sides guarantees excellent solderability and protection against corrosion, while the 950mm width allows for efficient material utilization in production lines.
Key Features & Technical Specifications
- Precise Thickness Control: 0.15mm ± 0.005mm tolerance ensures consistent material flow during forming processes.
- T1 Temper Grade: Provides moderate hardness and excellent elongation, minimizing cracking in deep-drawn battery cases.
- Uniform Tin Coating: 1.1/1.1 g/m² on both sides, meeting the requirements of dry battery internal resistance and corrosion protection.
- 950mm Width: Optimized for typical battery case blanking dies, reducing scrap and increasing yield.
- Surface Finish Options: Available in bright or matte finish upon request, to suit different soldering or printing needs.
- Flatness & Edge Quality: Strictly controlled to prevent burrs and waviness, ensuring smooth feeding in automatic presses.
- Compliance with International Standards: Manufactured in accordance with ISO 11949 and JIS G3303, ensuring global acceptance.
- Application-Specific Formulation: Steel chemistry tailored for dry battery case applications, with low carbon content for high ductility.

Advantages for Dry Battery Case Manufacturing
- Excellent Deep Drawability: The T1 temper and low-carbon steel base ensure uniform material flow, reducing the risk of wrinkling or tearing during case forming.
- Reliable Solderability: The uniform 1.1/1.1 g/m² tin coating provides a clean surface for soldering battery terminals, ensuring low electrical resistance.
- Corrosion Resistance: The tin layer acts as a barrier against moisture and electrolyte leakage, extending battery shelf life.
- Cost-Effective Material Utilization: The 950mm width is designed to maximize the number of battery case blanks per sheet, reducing waste and lowering unit cost.
- Consistent Quality: Our ISO9000 and ISO19011:2000 quality management systems ensure that each batch meets strict dimensional and coating specifications.
- Global Logistics Support: With ports of shipment in Qingdao, Tianjin, and Shanghai, we deliver efficiently to main markets including North America, South America, Europe, Southeast Asia, Africa, and the Middle East.
Compared to ordinary tinplate, our product is specifically optimized for dry battery case applications. The combination of 0.15mm thickness, T1 temper, and 1.1/1.1 g/m² coating provides the ideal balance of strength, formability, and corrosion protection. Many battery manufacturers have reported improved production yields and reduced tooling wear when switching to our sheets.

Frequently Asked Questions (FAQ)
-
Q: What is the typical lead time for this tinplate sheet?
A: For standard dimensions (0.15mm x 950mm sheet), the lead time is usually 15–20 days after order confirmation. Customized sizes may require 20–25 days. We maintain buffer stock to expedite urgent orders. -
Q: Can you provide samples for testing before bulk order?
A: Yes, we offer free samples (approximately A4 size) for evaluation. The customer is responsible for shipping costs. Please contact us to request a sample with your specific requirements. -
Q: Is this tinplate suitable for alkaline battery cases as well?
A: While primarily designed for dry battery (carbon-zinc) cases, with proper surface treatment, it can also be used for some alkaline battery components. We recommend testing with your specific forming process. -
Q: What is the minimum order quantity (MOQ)?
A: The MOQ for sheets is 10 metric tons. For coil form, the MOQ is 20 metric tons. Smaller trial orders are possible after discussion. -
Q: How do you ensure the tin coating uniformity?
A: We use advanced electrolytic tinning lines with real-time coating weight monitoring. Each coil is tested by X-ray fluorescence (XRF) to ensure the 1.1/1.1 g/m² specification is met. -
Q: What packaging options are available?
A: Standard packaging includes wooden pallets with steel strapping and waterproof wrapping. For export, we use seaworthy packaging with anti-rust paper and plastic film. Custom packaging (e.g., pallet weight, labeling) is available upon request. -
Q: Can you supply tinplate in coil form instead of sheets?
A: Yes, we can supply in coil form with the same specifications. Coil weight up to 10 tons, with inner diameter 508mm or 610mm. Please specify your preference. -
Q: Do you have any certifications for environmental compliance?
A: Our production processes comply with ISO 14001 environmental management standards (upon request). We can provide material safety data sheets (MSDS) and declarations of conformity for RoHS and REACH upon request.
