Quick tip: the minus sign in mesh sizes (e.g. -200) means the powder passes through that sieve, so -200 mesh means every particle is smaller than 75 µm.

Frequently Asked Questions

AL-SP

Questions & Answers

What is AL-SP spherical aluminium powder used for?

AL-SP is used in thermal spray and cold spray coatings, additive manufacturing (SLS, binder jetting, DED), decorative aluminium finishes and aerospace components. Gas-atomised spherical morphology gives the free flow those processes require.

What grades and particle sizes are available?

AL-SP is supplied at Al 99.0% minimum purity in -100, -200 and -325 mesh, plus AM-specific 15-45µm and 45-90µm cuts with laser diffraction PSD data. Apparent density runs 1.2 to 1.6 g/cc.

Is AL-SP safe to handle?

Fine aluminium powder is combustible and must be handled to the guidance in the Safety Data Sheet: earthed equipment, no ignition sources and appropriate dust controls. The SDS is supplied with every order and available on request before purchase.

Can AL-SP be used for additive manufacturing?

Yes. The 15-45µm cut suits laser powder bed fusion and the 45-90µm cut suits electron beam and directed energy processes, both with the sphericity and flow that AM feed systems depend on.

Can I order small or sample quantities of AL-SP?

Sample quantities are available for process trials. UK stock grades typically dispatch within 48 hours in 1 kg, 5 kg or 25 kg packaging.

What documentation is supplied with AL-SP?

ISO 9001 certified documentation, chemical analysis and batch traceability with every shipment, plus Safety Data Sheets and hazardous goods shipping guidance for export orders.
