Most excavator buckets are made from wear-resistant steel specifically designed to withstand the tough conditions of digging, impact, and abrasion. This type of steel is tougher and more durable, helping to extend the life of the bucket even with constant use. If you're looking at a specific bucket, it's always a good idea to check the specifications or ask the manufacturer about the materials used. That way, you can ensure it's built to handle the job you have in mind!
