Why is the material important in stamping?

A brief introduction to the key role of materials in determining the success or failure of stamping projects.

Material properties determine the success or failure of the project

One of the most critical decisions when starting a stamping project is the selection of materials. This is not just a formal decision, but one that affects the success or failure of the project. The reasons are as follows:

Strength and durability: Imagine creating a beautiful component, only for it to deform or break under the slightest pressure. The strength of the material determines its ability to withstand external forces. Whether it is the pressure of stamping or the stresses faced in the final application, the material must maintain its shape and integrity. For example, automotive parts require materials that can withstand the harsh environment of daily use without deformation.

Ductility: On the other hand, while strength is crucial, the material's ability to be shaped is also vital. Ductility refers to the ease with which a material can be stamped, bent, or formed without breaking or cracking. This is particularly important for complex designs or when a high level of detail is required. Too brittle materials may shatter under the stamping press, leading to the waste of resources and time.

Corrosion resistance: No one wants their stamped products to degrade prematurely. Corrosion, which is the gradual destruction of a material due to a chemical reaction with the environment, is a real concern, especially for products exposed to moisture, certain chemicals, or varying pH levels. For example, ship equipment or parts used in chemical factories require materials that are resistant to rusting or corrosion.
