Beryllium Copper C17300: DOMADIA™ CuBe2Pb Alloy M25 Explained
Everything was going fine… until it wasn’t.
Your usual copper alloy—reliable as an old friend—starts ghosting your performance expectations. Missed specs. Worn-out tools. Tight deadlines tightening further.
Just when you think the project’s about to pull a full Titanic…
In walks DOMADIA™ Beryllium Copper C17300 like it owns the place.
With machinability so smooth it makes butter jealous, and the strength of a caffeine-fueled engineer on deadline day, it flips the script and delivers parts so precise they make calipers cry.
🧪 What is DOMADIA™ Beryllium Copper C17300 (CuBe2Pb – Alloy M25)?
DOMADIA™ C17300 is a precipitation-hardened beryllium copper alloy with lead (Pb) added to enhance machinability. This alloy offers excellent strength, electrical and thermal conductivity, and is ideal for precision components across industries.
✅ Compared to conventional copper alloys or brass, beryllium copper strength is significantly higher, with tensile strength reaching up to 1380 MPa.
