Blog FAQs
How the blog relates to quotations, samples, and technical support.
Is the blog written by your engineering team?+
Yes. Articles are written by the Weison engineering and sales team based on the questions buyers ask during RFQ review, grade selection, and production planning.
Can I ask a question that is not covered in an article?+
Yes. Send the question with your drawing or application description to sales@tungstenmetal.com or through the RFQ form, and the relevant engineer will answer directly.
Do the guides apply to custom parts as well as standard products?+
Yes. The material logic in the guides applies to both standard forms and drawing-based custom parts; for custom supply, the RFQ checklist article is the practical starting point.
Have a question the articles do not answer?
Send the drawing, grade question, or application description. Our sales engineers reply with a practical material and supply direction.
