Frequently asked questions
What sample size do you require for Mechanical Testing?
Sample size requirements vary depending on the type of test and the applicable standards. However, our general guidance is:
- Tensile Testing: Minimum 13 mm square or diameter × 53 mm in length
- Flat/Sheet Material Testing: Ideally 10 mm wide × 70 mm long
These are typical dimensions, but we may be able to accommodate smaller samples on a case-by-case basis.
Not sure if your sample is suitable? Get in touch — our team will be happy to advise.
What is the turnaround time for Mechanical Testing?
Standard turnaround for Mechanical Testing is 3–5 working days from sample receipt. For urgent needs, we offer same-day and next-day premium services, for expedited results at an additional cost.
Can you test small quantities of one-off samples?
Yes, we can accommodate smaller quantities or one-off samples. Whether you have a single sample or a limited batch, we are flexible and can tailor our Mechanical Testing service to meet your needs.
What types of metals can be tested with Mechanical Testing?
We can test a wide range of ferrous and non-ferrous metals, including:
- Carbon & Alloy Steels
- Stainless Steels
- Cast Iron
- Aluminium & Alloys
- Copper Alloys (e.g. brass, bronze)
- Nickel, Titanium & Superalloys
- Magnesium, Zinc & more
If you’re unsure whether your metal is suitable, just contact us — we’re happy to help.
How do I prepare my sample for Mechanical Testing?
You don’t have to — we can do it for you. Our in-house machine shop can cut, shape, and finish your metal samples to the correct specifications, saving you time and ensuring they’re prepared to the highest standards.
Sample preparation involves selecting the correct metal, cutting it to the required dimensions, ensuring it’s free from defects, and sometimes applying specific surface treatments to simulate real-world conditions. The preparation method depends on the specific test being conducted.
Already have prepared samples? We can test those too. If you’re unsure what’s needed, just get in touch and we’ll guide you through it.
Are there any Mechanical Tests that you don’t offer?
Unfortunately, we do not currently offer the following Mechanical Tests.
- Fatigue testing (cyclic loading)
- Creep testing
- Vibration or Shock Testing
These tests require specialised equipment and conditions that are currently outside of our scope of testing capabilities.
What industries use Mechanical Testing?
Mechanical testing of metals is critical across many industries to ensure performance, durability, and safety in demanding applications.
Key industries include:
- Automotive: Tests metal components like chassis, suspension, and engine parts for strength.
- Aerospace: Evaluates high-strength, lightweight metals (e.g., titanium, aluminium alloys) for stress, and performance under extreme temperatures.
- Construction & Civil Engineering: Assesses structural metals (steel beams, rebar) for load-bearing capacity, ductility, and failure resistance.
- Manufacturing & heavy equipment: Tests tool steels and industrial alloys for wear, impact resistance, and mechanical integrity in moving parts and machinery.
- Energy & Power (Oil, Gas, Nuclear): Subjects metals to high-pressure, high-temperature, and fatigue tests—especially pipeline steels and turbine alloys.
- Rail, Marine & Transport: Evaluates metals for fatigue, corrosion resistance, and structural integrity in rail tracks, ship hulls, and heavy vehicles.
Why is Mechanical Testing important?
Mechanical Testing is critical to understanding how metals perform under real-world conditions, and to ensuring they’re fit for purpose.
Whether it’s a fastener, a structural component, or a safety-critical part, knowing how a metal behaves under stress, strain, impact, or fatigue is essential for safe and reliable design.
By measuring key mechanical properties of materials like strength, hardness, ductility, toughness, and elasticity, these tests provide vital data to help:
- Ensure product quality and consistency
- Verify compliance with industry standards and specifications
- Optimise metal selection and design for performance and durability
- Investigate failures and prevent future issues through root cause analysis
