What Machined Tungsten Parts Cost and What Drives the Price

September 20, 2026 · Reviewed September 26, 2026

A machined tungsten part costs more than the same part in steel, often by a wide margin. The reasons are predictable. Once you know how a tungsten quote is built, you can read it properly and often change the drawing or the order to bring the price down.

This guide does not list prices per part. Tungsten prices move with the raw material market and every part is different. It explains the six things that decide the number on your quote.

1. The price of tungsten itself

On most machined parts, material is a small share of the price. On tungsten parts it can be the largest share.

Tungsten heavy alloy costs many times more per kilo than carbon or stainless steel. Pure tungsten costs more again. And because tungsten is so dense, the same shape weighs a lot more. A heavy alloy part weighs more than twice as much as the same part in steel. So you pay a higher price per kilo on more kilos.

Two consequences for buyers:

Weight matters more than size. A small, thick shield can cost more in material than a large thin bracket in aluminum.
Material price changes show up in quotes. Tungsten raw material prices move over time. If you get a quote today and order in three months, ask how long the price is valid.

2. The starting shape of the blank

Machining tungsten from a solid bar turns expensive material into chips. The chips have scrap value, but far less than the price of the bar.

Tungsten mills can press and sinter blanks close to the final shape. A near-net blank leaves only a few millimetres to machine, which saves:

Material, because less is bought and less is cut away.
Machine time, because tungsten cuts slowly.
Tool wear, which is significant on tungsten.

The trade-off is tooling. The mill may charge for a pressing die. For one or two parts that makes no sense. For dozens or hundreds of the same part it often pays back quickly. When you send an RFQ with a meaningful quantity, ask the shop whether a near-net blank would lower the total price.

3. How the part is cut

Different grades need different processes, and those processes have very different hourly costs and speeds.

Grade	Main process	Effect on price
Heavy alloy	CNC turning and milling	Lowest of the group
Tungsten copper	CNC turning and milling	Similar to heavy alloy
Pure tungsten	Careful milling plus grinding or wire EDM	Higher, with more scrap risk
Tungsten carbide	Grinding and EDM	Highest per feature

Pure tungsten is brittle at room temperature. Shops run light cuts to avoid chipping and cracking, and a scrapped tungsten part is an expensive loss. Quotes on pure tungsten often include a margin for that risk.

If your part is tungsten for density rather than for heat, specifying heavy alloy instead of pure tungsten is usually the biggest single saving available.

4. Tolerances and surface finish

Every tolerance tighter than the process holds naturally adds cost. It adds slower passes, more inspection and more scrap. On tungsten each of those costs more than on steel.

Common patterns that raise tungsten quotes:

A general tolerance block of ±0.01 mm applied to every dimension, when only two bores matter.
Fine surface finish callouts on faces nobody sees.
Sharp external corners on pure tungsten, which chip and need rework.
Flatness or parallelism callouts on large faces that force a grinding step.

Tolerance what matters to function and let the rest follow the shop’s standard. Add small chamfers to outside edges on pure tungsten parts.

5. Quantity

As with any machined part, setup and programming are paid once per order. On one or two parts they can be most of the price. As quantity rises, that fixed cost is spread over more parts and the price per part drops quickly.

With tungsten, quantity also decides the blank strategy. Past a few dozen parts, the switch from bar stock to a near-net blank can drop the price per part further than setup savings alone.

If you expect repeat orders, say so in the RFQ. A shop quoting 20 parts once prices differently from a shop quoting 20 parts four times a year.

6. Certs, tests and inspection

Many tungsten parts go into regulated or safety-related uses: medical imaging, radiotherapy, aerospace and radiation sources. Those uses bring paperwork.

Each of these adds cost and usually a few days of lead time:

Material certificates to ASTM B777 or your own spec.
Density testing, which confirms tungsten content on heavy alloy parts.
Radiographic or dye penetrant inspection to check shielding parts for internal voids or cracks.
First article inspection reports and dimensional reports on every lot.

Ask only for what your customer or your quality system requires. Put the list in the RFQ so every shop quotes the same scope.

Lead time and rush orders

Lead time affects price more on tungsten than on common metals. Few mills make tungsten blanks, and a near-net blank has to be pressed and sintered before machining can start. A shop that has suitable bar in stock can start at once. A shop that has to order a blank may need several weeks before the first cut.

When you need parts fast, the shop usually cuts from whatever stock is on hand. That can mean a larger blank, more material cut away and a higher price per part. Rush work also pushes other jobs aside, and most shops charge for that.

If your schedule allows it, give the shops a realistic date rather than “as soon as possible”. A few extra weeks can let a shop order the right blank size, which lowers both material and machine time. If you order the same part every year, ask whether the shop can hold blanks in stock for you. That moves the waiting time out of your next order.

For prototypes, the opposite trade often makes sense. Paying more per part to cut from stock bar gets a first article in your hands sooner, and you can switch to near-net blanks once the design is frozen.

How to compare tungsten quotes fairly

Quotes for the same tungsten part can differ a lot. Before you decide, check that they cover the same things:

Same grade and class. A quote in W-Ni-Fe is not comparable with one in W-Ni-Cu or pure tungsten.
Same material source. Is the blank included, or are you expected to supply it?
Same blank strategy. Bar stock or near-net blank, and who pays for tooling.
Same tests and paperwork. Certs, density tests and inspection reports.
Same validity period. Tungsten prices move, so a longer validity may carry a margin.

Drawing changes that lower the price

Before you send the RFQ, go through this list:

Use heavy alloy unless heat is the reason you need tungsten.
Loosen tolerances on features that do not affect function.
Add chamfers or radii to sharp external edges.
Avoid walls thinner than about 1 mm, especially in pure tungsten.
Replace small deep holes with larger or shallower ones where the design allows.
Give realistic annual volume so shops can consider a near-net blank.

Frequently asked questions

Why is a tungsten part so much more expensive than the same part in steel?

Two reasons stack up. Tungsten heavy alloy costs many times more per kilo than steel, and a tungsten part weighs more than twice as much as the same shape in steel. On top of that, tungsten cuts slower and wears tools faster, so machine time is higher too.

Is pure tungsten more expensive to machine than heavy alloy?

Usually yes. Pure tungsten is brittle, so shops cut it slowly, scrap more parts and often finish features by grinding or wire EDM. The same part in heavy alloy is normally cheaper and faster to make, if the application allows it.

How can I lower the price of a machined tungsten part?

Use heavy alloy instead of pure tungsten where heat is not the reason for tungsten, loosen tolerances that do not affect function, add chamfers to sharp edges, avoid thin walls and ask whether a near-net sintered blank makes sense for your quantity.
