Yes, trial orders are available for most products, excluding custom-engineered alloys. Please select the “Trial quantity required” option when submitting your RFQ form.
Lead times vary depending on the type of order. Below is an overview of typical processing and delivery times for our main order categories:
- Trial batch orders are typically dispatched within 5 business days from the date of payment receipt.
- Ultra high-purity metals purchase orders are fulfilled within 7–14 business days from the date of advance payment under the main agreement, depending on quantity and destination.
- Custom alloy wire manufacturing orders include a development phase and are scheduled individually based on product complexity, specification, and volume.
Lead time for each custom alloy wire contract is determined jointly with the client and includes both production and quality assurance stages.
Yes, we can arrange logistics and deliver to any international airport specified by the buyer.
Our order processing follows a structured and transparent workflow aligned with Incoterms 2020 practices:
- Client: submits an LOI (Letter of Intent) or RFQ form to Pure Metals.
- Jointly: we clarify and confirm all technical and commercial details of the LOI/RFQ.
- Pure Metals: issues an FCO (Full Corporate Offer). We intentionally skip SCO (Soft Corporate Offer) to streamline the process.
- Client: confirms the FCO and provides proof of funds (BCL or equivalent banking document).
- Optionally: a trial quantity shipment may be arranged under an accelerated procedure, based on a simplified standalone agreement. Upon receipt, the client confirms that the product quality meets the required specifications.
- Pure Metals: drafts the contract and coordinates revisions with the client.
- Both parties: sign the final contract.
- Client: makes a partial advance payment — typically 25% of the total value of the initial product batch.
- Pure Metals: dispatches the goods and provides the transport documentation to the client.
- Client: completes final payment and receives the goods at the destination in accordance with the transport documentation and agreed delivery terms.
Absolutely. Once your RFQ or LOI is agreed upon and the FCO is signed, we’d be happy to arrange a visit to one of our warehouses that best suits your order specifics. If needed, we can also organize self-pickup of your order from the warehouse under the appropriate Incoterms 2020, making the process as smooth and convenient for you as possible.
Yes, we assist with all necessary documentation to help streamline logistics, compliance, and customs clearance — regardless of the products combination or technical specifications in your order.
Yes, every delivery includes a lab certificate to verify product purity and ensure batch-to-batch consistency.

Ultra High-Purity Zinc Powder: Material Profile
Zinc powder (5N / 6N) is a precision-engineered metallic material designed for the most demanding technological and scientific applications. Derived from natural zinc with controlled isotopic composition, the powder undergoes rigorous multi-stage refining to achieve purity levels of 99.999% (5N) and 99.9999% (6N), minimizing trace element interference and ensuring consistent performance.
Zinc, a Group 12 transition metal, has a melting point of 419.5 °C and a boiling point of 907 °C. In its ultra-high-purity powder form, zinc’s electrical, chemical, and nuclear properties become highly predictable and reproducible. This makes it essential where even sub-ppm impurities could affect system functionality, measurement accuracy, or material behavior.
Product Form and Handling
High-purity zinc powder typically features particles sized in the low micrometer range, with morphologies varying from near-spherical to dendritic. These physical characteristics influence powder flow, packing density, and reactivity during processing. The powder’s high surface area and chemical purity enable its use in sensitive applications including semiconductor manufacturing, specialty alloys, advanced coatings, and radiopharmaceutical precursors requiring exact isotopic control.
Given zinc powder’s sensitivity to oxidation and moisture, it is carefully packaged in hermetically sealed PET containers for smaller volumes and vacuum-tight glass vessels for bulk shipments. Such packaging preserves the powder’s purity and functional properties throughout storage, handling, and transport, ensuring reliable performance in high-precision industrial and scientific environments.
Applications of Pure Zinc Powder (5N–6N)
Ultra high-purity zinc powder, with purity levels of 99.999% (5N) and above, offers exceptional chemical stability and consistent isotopic composition, making it indispensable for advanced technological and scientific applications. Below are key sectors where this material plays a critical role:
