Cymbals 2. B20 bronze — the professional standard — B20 bronze is roughly 80% copper and 20% tin. It is the alloy behind most professional cast cymbal lines — including Zildjian's proprietary cast-bronze alloy, Meinl's Byzance series, and the top tiers of Sabian and Paiste — and is prized for a darker, more complex tone with a wide spread of overtones. It is harder to work than lower-tin alloys, which is part of why B20 lines carry a professional price point.3. B8 bronze — the brighter, more affordable option — B8 bronze uses far less tin — about 92% copper to 8% tin — which makes it easier and cheaper to roll into sheets and stamp into cymbal blanks. The result is a brighter, more immediate, less harmonically complex sound than B20, which is why B8 shows up almost exclusively in entry-level and student lines rather than professional ones.4. Brass and the B12 middle ground — Brass (a copper-zinc alloy rather than a copper-tin bronze) is the softest and brightest of the common cymbal materials, and is reserved for the most basic beginner packs. Between B8 and B20 sits B12 bronze (about 88% copper, 12% tin) — used by some mid-tier lines to land between the two extremes: more shimmer and definition than B8, without the cost of a full B20 cast line.5. Cast vs sheet — how a cymbal is actually made — Cast cymbals are individually poured from raw molten alloy, then hammered and lathed by hand (or by controlled machine process) into their final shape — a slower, more expensive process that produces more complex, cymbal-to-cymbal-varied tone and is generally associated with better durability under sustained hard hitting. Sheet cymbals are cut from pre-rolled, uniform-thickness sheets of metal, which is faster and cheaper but produces a more uniform, simpler sound. Higher-tin alloys like B20 are almost always cast; lower-tin alloys like B8 are almost always sheet.6. B20 vs B8 — what is the difference? — B20 bronze (80% copper, 20% tin) is cast and produces a darker, more complex professional tone; B8 bronze (92% copper, 8% tin) is cut from sheet metal and produces a brighter, simpler, more affordable sound. B20 dominates professional cymbal lines; B8 dominates entry-level and student lines.7. What is the difference between cast and sheet bronze cymbals? — Cast cymbals are individually poured from molten alloy and then hand-shaped, giving a more complex tone and (generally) better durability under heavy playing. Sheet cymbals are cut from pre-rolled, uniform sheets of metal — faster and cheaper to produce, but simpler and brighter sounding, and typically less durable under sustained hard hitting.8. Are brass cymbals bad? — Brass cymbals are not "bad," but they sit at the very entry level of cymbal alloys — softer and brighter than even B8 bronze, with the least complex tone — and are mainly found in the cheapest beginner packs rather than any line built for serious or heavy playing.
