How thick of metal can a 50W fiber laser cut
Fiber lasers are the best option for laser cutting/engraving aluminum and brass workpieces.
Fiber laser machines are better at cutting thin metals than other types of cutting machines. A fiber laser machine is capable of cutting thin metals up to 25mm (or 1 inch). Fiber lasers then start to cut metal less efficiently. To cut ticker metals larger than 25mm or 1 in., you would require a high power laser, which will cost you a lot more.
