FAQ

Are you a factory or manufacturer?

A: Yes, we are a factory but generally, we use our trading company to handle the business abroad. It will be convenient to receive the remittance and arrange the shipment.

What is the delivery method?

A: Generally, we send cargo by UPS, DHL or FedEx. Also, we can send by sea to seaport or by air to the closest airport.

Why is your product so cost-effective?

A: We cut out the middlemen in the end-to-end manufacturing process. Rather than obtaining semi-finished goods from other suppliers, we obtain our raw material of APT powder directly from its source.

Do you do spot quality inspection or full inspection?

A: 100% full inspection. Inspectors will check the finished product individually, to ensure they adhere to all parameters. All unqualified products are discarded.

How do you ensure your lead time?

A: We have an efficient Order Management System, from material preparation to machining, and finally to a full inspection. Every stage of production is strictly monitored and controlled to give you an accurate delivery time.

What is the MOQ of Tungsten Copper Alloy W80Cu20 Rod?

A: Depends on quantity, generally, no MOQ limit.

How to pay for it?

A: A bank transfer (T/T) will be acceptable.

What is the delivery time?

A: around 7-20 days which depends on the quantity and production.

What is kind of the package?

A: Generally, we use a carton case or plywood case with protective material inside to ensure the save of cargo

What is the lead time?

A: from order placed to cargo receiving will take around 10-25 days.

Why choose W80Cu20 over pure tungsten or copper?

It balances tungsten's strength and copper's conductivity, making it more durable and easier to machine than pure tungsten while offering better heat resistance than pure copper.

Can the tungsten-copper ratio be adjusted?

Yes, changing the ratio (e.g., W70Cu30 or W90Cu10) can optimize properties like thermal expansion or conductivity for specific applications.

Is W80Cu20 magnetic?

No, it is non-magnetic, making it suitable for sensitive electronic and scientific applications.

How is W80Cu20 manufactured?

It is produced through powder metallurgy, including isostatic pressing, high-temperature sintering, and copper infiltration.
