Compare the detailed specifications of Al7075-T6, Al6061, brass and SUS304 stubs, and
check the risk of EDS peak overlap for the elements in your sample before you measure, so composition results stay clean.
MATERIAL COMPARISON
Machined hardness, surface flatness, vacuum suitability and key trace elements at a glance.
| Property | Al7075-T6 (high-strength Al) ✨ | Al6061-T6 (standard Al) | Brass (Cu-Zn) | SUS304 (stainless steel) |
|---|---|---|---|---|
| Typical use | BYSTECH premium stubs, made in Korea | Imported standard stubs (M2N) | Special grounding & wear resistance | High-temperature & corrosion-resistant work |
| Vickers hardness (HV) | HV ~175 (very high) | HV ~95 (medium) | HV ~150 (high) | HV ~200 (highest) |
| Surface flatness & machinability | Excellent (no burrs or scratches when machined) | Good (standard machining) | Fair | Fair (difficult to machine) |
| Main elements (alloy composition) | Al (base), Zn (5.6%), Mg, Cu | Al (base), Mg (1.0%), Si, Fe | Cu (60%), Zn (40%), Pb | Fe (base), Cr (18%), Ni (8%) |
| Elements to watch in EDS | Watch Zn and Cu peaks | Trace Mg, Si, Fe peaks | Strong Cu and Zn peak interference | Strong Fe, Cr, Ni peak interference |
| Best suited to | R&D precision analysis, FIB lamellae, semiconductors | Routine production QA, teaching samples | Mounting special non-ferrous metals | Strongly acidic or high-temperature bio samples |
