Strategic material

Strategic material is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Strategic material rather than just read about it. In short: Strategic material is any sort of raw material that is important to an individual's or organization's strategic plan and supply chain management. Lack of supply of strategic materials may leave an organization or government vulnerable to disruption of the manufacturing of products which require those materials.

Key takeaways

Strategic material belongs to engineering; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Strategic material to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Strategic material from memory before moving on to harder problems.

Reference excerpt

Strategic material is any sort of raw material that is important to an individual's or organization's strategic plan and supply chain management. Lack of supply of strategic materials may leave an organization or government vulnerable to disruption of the manufacturing of products which require those materials. It can also refer to a group or department that manages these materials. The term "critical material" is increasingly used rather than "strategic material". In government terms, they are materials, usually raw materials that have a particular strategic significance to a government or nation, often in time of war. Their strategic need is because of their crucial importance for either economic or military purposes. Some materials are relatively simple to procure or produce, but are required in great quantities during wartime. Others are obscure and technically complex to obtain or create. Although not required in large quantities, their irreplaceability and critical need makes them especially valuable. Foodstuffs are not generally classed as strategic materials: although vital, they are treated separately. Techniques for replacing strategic materials with ersatz substitutes have become highly important. These also include the minimisation of or the recovery and recycling of such materials. As well as depending upon strategic materials, warfare may be carried out with their specific goal in sight. Japanese expansion in World War II targeted rubber crops and their plantation areas in particular. Conflict between Germany and France has repeatedly focussed upon the iron and steel bulk resources of their border region.

Government approaches

United States The US Defense Logistic Agency manages strategic materials for the US military. The United States critical materials list is a designation of materials or minerals considered essential for the economic or national security of the United States, where there is a high risk of supply chain disruption.

European Union

Since 2011, the European Commission has triennially assessed a list of Critical Raw Materials (CRMs), with 14 CRMs identified in 2011, 20 in 2014, 27 in 2017, 30 in 2020 and 34 in 2023. These materials are mainly used in energy transition and digital technologies. These are primarily materials used in energy transition and digital technologies. Then, in March 2023, Commission President Ursula von der Leyen proposed the Critical Raw Materials Act, "for a regulation of the European Parliament and of the European Council establishing a framework for ensuring a secure and sustainable supply of critical raw materials".

Australia

In 2024 the Australian government announced a "Future Made in Australia" initiative as a new industrial policy for Australia, supporting manufacturing and exploitation of critical mineral resources as part of Australia's renewable energy transition. The Australian government maintains a Critical Minerals List of 32 minerals 'essential to our modern technologies, economies and national security' and a Strategic Materials List of five minerals 'important for the global transition to net zero and broader strategic applications'.

In business Strategic materials encompass a subset of raw materials required to make a product. The strategic materials may be limited in number or subject to shortages. In this case, the strategic plan would call for an alternative supply chain or alternative materials in the event of a breakdown in the current supply chain.

Worked examples

Example 1 — a first encounter with Strategic material

Start with the simplest possible case. Write down what Strategic material claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Strategic material before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Strategic material ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Strategic material

In research: Strategic material appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Strategic material in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Strategic material is common in secondary-school and first-year university syllabi. It links to neighbouring topics Minerals, Natural materials, Supply chain management, so understanding it makes those chapters shorter.
In everyday life: Look for Strategic material outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.

Frequently asked questions

What is Strategic material in simple terms?

Why does Strategic material matter?

Because it connects several engineering ideas at once: it gives you a definition you can apply, a quantity you can calculate, and a way to check whether a result is plausible.

How should I study Strategic material?

Read the excerpt, restate it from memory, then work through the examples and applications listed on this page. The five-step study plan above takes about twenty minutes.
