Durable Technologies does not offer or recommend alloy types like lead or zinc. Not only is the process of producing alloy type unhealthy, this material is just not made to our high standards of quality. Alloy or lead type is also referred to as service type or foundry type.
We're all familiar with the old adage that "You get what you pay for" and this couldn't be more true in this case. Lead type does not react well with heat and is known to melt, mushroom and even explode during use. Not to mention the rough and dull corners and edges that come with lead type, which translates into a poor-quality impression on your product. Alloy type may be less money up front but in the end brass is a much wiser investment. By the time you've replaced your lead type 3 or 4 times throughout the course of a year you will have already paid for the higher quality brass type that you should have started with!!
Our Brass and Steel Printers' Type is perfect for medium to long production runs and will outlast softer alloy metals like zinc and lead. Brass and steel will hold up much better when stamping under elevated levels of heat and/or pressure. Brass and steel type also produces a much crisper, cleaner mark than cheaper alloy types.

Magnesium dies are also available for shorter production runs.
