High Purity Tungsten Plate

To meet the precise needs of different customers, we create targeted product highlights. This page focuses on showcasing the application of high-purity tungsten plates in cutting-edge fields and reliable quality systems.

1 . Specially customized for semiconductor and high-temperature industries

• This product is specifically designed for manufacturing furnace tubes, heaters, and insulation screens for semiconductor diffusion furnaces and CVD equipment. Its high melting point and extremely low vapor pressure ensure stability and cleanliness in long-term high-temperature environments, ensuring the reliability of chip manufacturing processes from the source.
• At the same time, it is also an ideal choice for high-temperature industrial equipment such as sapphire growth furnaces and vacuum sintering furnaces, effectively improving equipment life and production efficiency.

2. Excellent density and radiation shielding performance

• With a high density close to theoretical values, this tungsten plate is a top-level material for manufacturing medical radiation therapy collimators, nuclear medicine protective covers, and industrial flaw detection shields. It can effectively attenuate and shield gamma rays and X-rays, providing safety protection for operators and the environment.

3. Authoritative quality certification, trustworthy commitment

• We are well aware of the strict requirements for material consistency in high-end applications. Each batch of high-purity tungsten plates undergoes strict ultrasonic testing and dimensional accuracy inspection before leaving the factory, and a third-party authoritative testing report is provided. We promise that the purity of our products will not be less than 99.95%, ensuring that every piece of board you receive has consistent performance and is reliable and worry free.

 

We understand that besides the product itself, you also care about how we manufacture it and how we ensure its quality. This section will provide a detailed introduction to our core production process and quality control system.
1. Top production process flow
Our high-purity tungsten plates follow a rigorous manufacturing process:
Isostatic pressure forming → High temperature pre sintering → Vertical melting sintering → Precision rolling → Stress annealing → Fine grinding and cutting
Among them, precision rolling and stress annealing are key processes that together determine the final internal grain structure, density, hardness, and stress state of tungsten plates, ensuring excellent high-temperature creep resistance and dimensional stability of the products.
2. Quality control throughout the entire process

• Incoming inspection: Conduct purity and particle size analysis on tungsten powder raw materials to ensure quality control from the source.
• Process inspection: After key processes such as sintering and rolling, sample and test the density and metallographic structure.
• Factory inspection:

Non destructive testing: Ultrasonic flaw detector is used to ensure 100% absence of cracks and delamination inside the product.
Dimensional inspection: Use precision measuring tools to ensure that thickness, flatness, and diagonal tolerances meet standards.
Performance verification: Conduct high-temperature performance testing on some batches to ensure their reliability under operating conditions.
3. Professional protective packaging and flexible logistics

• Packaging method: To ensure that the product is protected from moisture, impact, and scratches during transportation, we use "bubble wrap+moisture-proof paper" for primary wrapping, and then firmly fix it in a customized wooden box with desiccant inside. This packaging method is waterproof, shockproof, and can safely cope with long-distance transportation challenges.
• Transportation and Freight: We are committed to simplifying your procurement process and providing a true 'turnkey' solution. For this product, we solemnly promise that all quotations are inclusive of tax and freight. This means that the quotation you receive already includes all relevant taxes and fees, as well as the full international logistics cost to your designated port, without any hidden expenses. We have deep cooperation with multiple top international logistics partners and can flexibly arrange logistics solutions such as sea freight and air freight according to your time requirements, ensuring the safety and timely delivery of goods. This commitment aims to allow you to fully focus on the product itself and application development, without being distracted by complex logistics and tax issues.

After sales guarantee: We provide a 12-month warranty and lifetime technical support for all high-purity tungsten plates. We promise unconditional returns and exchanges for any issues caused by substandard materials, and ensure a quick response within 48 hours to provide you with full cycle professional support from installation to application, ensuring worry free procurement.
