What is it?

Scandium (Sc, atomic number 21) is classified with the rare earths because its chemical behavior and supply-chain characteristics track the lanthanides.

Its strategic value comes from the outsized effect of small scandium additions to aluminum.

Aluminum-scandium alloys deliver higher strength, improved weldability, better corrosion resistance, refined grain structure, and superior additive-manufacturing performance.

How is it made?

Nearly all scandium is recovered as a by-product from:

• titanium-dioxide process streams,
• nickel and cobalt processing,
• rare-earth ores,
• uranium-related residues,
• tailings and industrial waste.

Recovery requires leaching, impurity removal, solvent extraction or ion exchange, precipitation, and calcination to scandium oxide. Oxide can then be converted to metal or aluminum-scandium master alloy.

Where is it produced?

USGS estimates 2025 world scandium oxide production at about 80 tonnes.

China was the leading producer. Scandium-bearing intermediate material was also produced in the Philippines and refined in Japan. Canada operates North America’s established commercial scandium-oxide source at Sorel-Tracy.

At this scale, individual plants — rather than country statistics — define the market’s strategic structure.

Notable sources & producers

Source / producer	Strategic significance
Hunan Oriental Scandium / LB Group — China	Operates a 40-t/year high-purity scandium-oxide facility and extensive alloy capacity.
Rio Tinto — Sorel-Tracy, Quebec	First North American commercial scandium-oxide producer; recovery from titanium-processing waste.
NioCorp — Elk Creek, Nebraska	2026 feasibility study projects 118 t/year scandium oxide over a 40-year mine plan.
U.S. Defense Logistics Agency / Sorel-Tracy	Planned procurement of more than 6,000 kg scandium oxide over five years for the National Defense Stockpile.
Nyngan, Australia	Dedicated scandium project with a mining license granted in 2025.

What is it used for?

• aluminum-scandium aerospace alloys
• additive-manufacturing powders and wire
• missiles and hypersonic systems
• aircraft and spacecraft structures
• solid oxide fuel cells
• high-intensity lighting
• ceramics
• lasers
• electronics
• sporting goods

Why is it important?

Scandium solves a specific materials problem: how to make aluminum stronger and more weldable without accepting the mass of titanium.

That matters directly to aircraft, missiles, spacecraft, propulsion systems, and additive manufacturing.

The Pentagon stated in 2025 that scandium alloys are increasingly replacing titanium and legacy aluminum components because of their lightweight, high-strength properties.

Is there a substitute?

Yes, with material tradeoffs.

Titanium, high-strength conventional aluminum alloys, and carbon-fiber composites can replace Al-Sc in many structures.

Al-Sc alone combines low density, weldability, additive-manufacturing behavior, corrosion resistance, and strength in one material.

How is it transported?

Scandium oxide and alloy are high-value, low-volume materials. Road and air transport are commercially important; sea freight serves larger contract shipments.

Its high value-to-mass ratio keeps it independent of bulk rail and port infrastructure.

Transportation risks

The primary risk is the small number of qualified producers.

A plant outage or export restriction can remove a meaningful share of world supply because annual global production is measured in tens of tonnes.

How long does it store?

Scandium oxide stores for years in sealed dry containers.

Scandium metal and alloy require standard reactive-metal protection; fine powders used in additive manufacturing demand strict moisture, ignition, and dust controls.

Historical price behavior

USGS scandium-oxide price ranges:

Year	$/kg
2021	$890–1,000
2022	$820–880
2023	$700–740
2024	$660–670
2025	$640
Aug. 27, 2026 SMM	$590.92

Prices fell as Chinese and by-product capacity expanded, but the market remains illiquid and contract pricing can differ substantially by purity and volume.

Current Price & Market — August 28, 2026

SMM assessed scandium oxide at $564.65–617.18/kg, averaging $590.92/kg on August 27.

5N scandium oxide averaged $669.70/kg, while 6N material averaged $689.40/kg.

Scandium metal averaged about $3,086/kg.

The market is simultaneously moving toward larger strategic demand. NioCorp and Lockheed Martin signed an August 4 MOU covering potential purchases of up to 15 tonnes/year of scandium oxide or equivalent alloy for ten years.

Strategic risks

1. The market is extremely small.
2. China directly controls scandium exports through licensing.
3. Most supply is by-product supply, so output responds to another industry’s economics.
4. The United States is fully import reliant today.
5. Aerospace qualification takes years.
6. Large new demand can exceed existing world production quickly.
7. New projects face a circular problem: consumers hesitate without supply, while producers hesitate without committed demand.

What can move the market?

Watch Chinese licensing, Rio Tinto expansion, NioCorp financing and construction, U.S. defense stockpile purchases, Lockheed Martin qualification work, fuel-cell demand, and adoption of Al-Sc powders in additive manufacturing.

Xin.bz bottom line

Scandium is one of the smallest commodity markets in this series — and that is exactly why it is strategically dangerous.

A few dozen tonnes support a global technology class. A single large aerospace adoption program can change the demand balance. A single new mine can change the supply balance.

Scandium is a strategic materials bottleneck where market size itself is the central vulnerability.
