As a professional manufacturer based in Qingdao, China, Shandong Sino New Material Co., Ltd. has been delivering high-quality steel products since 2018. With a factory spanning 10,000-30,000 square meters and a dedicated team of 101-200 employees, we specialize in the production of Tinplate Sheet 0.18mm x 850mm Width MR Grade T2.5 Temper 2.8/2.8g/m², specifically engineered for electronic parts manufacturing. Our tinplate sheets combine extreme precision, consistent mechanical properties, and excellent corrosion resistance, making them an ideal choice for components requiring reliable performance in compact electronic devices.
This product is manufactured using MR grade low-carbon steel, which offers superior formability and weldability. The 0.18mm thickness and 850mm width are optimized for high-speed stamping and deep drawing processes commonly used in the electronics industry. The T2.5 temper ensures a balanced hardness that provides both rigidity and ductility, while the 2.8/2.8 g/m² tin coating delivers a uniform protective layer against oxidation and corrosion, extending the lifespan of electronic components.
Our tinplate sheets are produced under strict quality control systems certified by ISO9000 and ISO19011:2000, ensuring traceability and consistency from coil to final product. Below are the key technical specifications:
| Parameter | Value |
| Thickness | 0.18 mm ± 0.005 mm |
| Width | 850 mm (customizable upon request) |
| Steel Grade | MR (DIN 1623, JIS G3303 equivalent) |
| Temper | T2.5 (Rockwell HR30T 55-60) |
| Tin Coating | 2.8/2.8 g/m² (both sides, differential optional) |
| Surface Finish | Bright (B) or Matte (M) – available on request |
| Coil Weight | 3,000 – 8,000 kg per coil |
| Application | Electronic components, battery connectors, shielding cans |
Key Features & Benefits:
- Ultra-Thin Precision: The 0.18 mm thickness allows for manufacturing of miniature electronic parts with tight tolerances, reducing material waste and improving production efficiency.
- Uniform Tin Coating: The 2.8/2.8 g/m² coating provides excellent solderability and corrosion resistance, essential for electronic components exposed to humidity or chemical environments.
- Optimized Temper T2.5: Combines moderate hardness with good formability, enabling complex stamping and bending without cracking – ideal for connectors, terminals, and shielding frames.
- Consistent Mechanical Properties: MR grade steel ensures stable yield strength (180-240 MPa) and elongation (≥30%), which guarantees repeatable performance in high-volume production runs.
- Wide Width Availability: The 850 mm width can be slit into narrower strips as per customer requirements, providing flexibility for different tooling setups.
- Certified Quality: Produced under ISO9000 and ISO19011:2000 management systems, with full traceability from raw material to final packaging.
Our tinplate sheets are shipped from major Chinese ports (Qingdao, Tianjin, Shanghai) in seaworthy export packaging – either wooden pallets or steel crates, with anti-rust paper and polybag protection. Each coil is clearly labeled with dimensions, weight, and heat number for easy identification.

Frequently Asked Questions (FAQ):
-
Q: What is the typical lead time for this tinplate sheet?
A: For standard specifications (0.18mm x 850mm, T2.5, 2.8/2.8g/m²), the lead time is approximately 15-20 working days after order confirmation. Custom sizes may require additional time. -
Q: Can you provide samples for testing before bulk order?
A: Yes, we offer free samples (courier cost paid by customer) of A4 size sheets or small coils. Please contact our sales team to arrange. -
Q: Is this tinplate suitable for food contact applications?
A: While MR grade tinplate is commonly used for food cans, our current product is optimized for electronic parts. For food-grade applications, we recommend our specialized line with higher purity tin coating. Please inquire for details. -
Q: What is the minimum order quantity (MOQ)?
A: The MOQ is 5 metric tons for standard dimensions. For non-standard widths or finishes, MOQ may be higher. -
Q: How do you ensure the tin coating is uniform across the sheet?
A: We use a continuous hot-dip tinning process with automatic coating weight control (X-ray gauge) and edge trimming to ensure uniformity within ±0.1 g/m². -
Q: Can this material be used for deep drawing applications?
A: Yes, T2.5 temper provides good ductility for moderate deep drawing. For severe forming, we recommend T1-T2 temper. Our technical team can advise based on your specific part design. -
Q: What packaging is used for export?
A: Each coil is wrapped in anti-rust paper, then with a polybag, and secured on a wooden pallet with steel strapping. For container shipment, we use shock-absorbing materials to prevent movement. -
Q: Do you have a quality certificate for each batch?
A: Yes, a Mill Test Certificate (MTC) with chemical composition, mechanical properties, and coating weight data is provided with every shipment, which is traceable to our ISO9000 system.
