Most quality products come with a guarantee or warranty these days. Cymbal companies too have warranties on their products. That means, if it breaks, they first of all want to know about it, and if it’s a quality issue they'll very likely send you a new cymbal.
BUT the breakage has to be their fault.
At one time, cymbal breakage was rare. People just plain played much less aggressively. And, to some extent they seemed to value their instruments more than seems to be the case with quite a number of contemporary players. Most companies will guarantee a newly purchased cymbal against certain types of breakage, but it ends there. If a player breaks a replacement cymbal, all love is lost and the cymbal will not be replaced. The rational is that the owner/player must be doing something wrong or just plain abusing their bronze.
If you find you're breaking a lot of cymbals, have a look at your cymbal set-up and how you hit. Your cymbals should be the correct size and weight for your music, and set up so that hitting with a glancing blow is the default.
Cymbal abuse comes in many forms, but the biggest issues are:
Improper mounting,
Too light for the job,
Over-playing leading to fatigue,
Hitting too hard,
Hitting directly on-axis.
Warranty Statements
Warranties are always limited. In the case of a cymbal, the maker will replace it if it is a manufacturing fault. There’s also a time limit, usually one or two years from the original date of purchase. That's pretty decent considering you're going to be beating these things regularly.
Sample Cymbal Warranty - from https://www.trurootcymbals.com. (Edited for length and clarity; emphasis added)
Limited 1-Year from the date of purchase
After inspection, [if] it is determined that your cymbal failed under normal use, a replacement will be provided. Typically, if a crack appears along the lathe lines it would fall under the scope of [the] warranty.
Warranty does not cover any misuse. If a crack appears cutting through the lathe lines, it would fall outside of the warranty, as the damage would have been caused from misuse.
To Claim A Warranty
If you feel the failure was due to defects in the material or workmanship, pack up the cymbal and dig the receipt out of the shoe box. Take both to the place of purchase or to another authorized dealer for that brand. The rep at the music store should be able to guide you through the process, and can arrange for the cymbal to be sent for evaluation and possible replacement.
The Reject Pile
Your claims may be rejected for any of the following reasons:
Excessive force or abuse (multiple cracks, edge cracks and cracks around the bell)
Improper transport or storage
Cymbals that have been dropped
A product that has been altered in any way
So take care of your cymbals and chances are your cymbals will take care of you.
