Learn How Materials are Used, and how to Choose the Best Materials for the Job
In order to make or repair anything you need to understand the materials available, the tools that can be used, and how to work with those tools to create the things you want to make.
Understanding the different properties of materials is very helpful in choosing materials for different purposes. It helps you select materials on the grounds of strength, malleability, thermal and electrical conductance or resistance, ease of cutting, and so on.
Many metals are provided in different sizes, shapes and grades. Size may be determined by thickness or gauge. Grade is an indication of composition and properties and is typically used for alloys. Part of the decision-making process involves selecting the right size and grade material for the job. Once you have chosen a material to use, you need to understand how to cut it, shape it, fix it (join it), and make it into something.
