For lead-free brass sawing, compare identified grades and their machining descriptions.
Lead-free brass sawing: materials
Wieland links eco SZ4’s machinability to its microstructure and selected composition.
Diehl links eZeebrass chip breaking to brittle Cu₂Mg phases produced by magnesium addition.

Neither description proves circular-saw cutoff performance or component suitability.

Order
Hypothetical blank order: a specified grade entry becomes merely “lead-free brass”.
Repeat the specified grade. Unnamed same-size stock is undefined; another named grade is an alternative.
