Basic Metal Properties and Selection

1. Tensile Strength

Tensile strength is the maximum stress that a material can withstand while being stretched or pulled before breaking. It is a critical property for metal fabricators, as it determines the load-bearing capacity of the metal. A higher tensile strength means the metal can handle more stress without failing.

For example, steel with a high tensile strength is often used in construction beams and suspension bridges because it can support heavy loads without deforming or breaking. In contrast, a metal with low tensile strength, like aluminum, might be used in applications where weight reduction is more important than load-bearing capacity, such as in aircraft components.

2. Corrosion Resistance

Corrosion resistance refers to a metal's ability to withstand the degradation caused by environmental factors such as moisture, chemicals, and air. Metals that are highly resistant to corrosion are essential in applications where exposure to harsh conditions is inevitable.

For instance, stainless steel is widely used in kitchenware and medical instruments because it does not rust easily, even when exposed to water and food acids. On the other hand, a metal like iron, which is prone to rusting, would not be suitable for these applications unless it is coated or treated to enhance its corrosion resistance.

Understanding these properties is crucial for metal fabricators when selecting materials for specific projects. By considering tensile strength and corrosion resistance, fabricators can ensure that their creations are both durable and long-lasting.
