The metals listed below are some of the most common metals used for forging steel knife blades
Copper: This metal is a good choice if you're looking to add some strength and resilience to your knife blade, but it's also one of the most expensive metals on our list. It can be found in many different alloys that give it a wide range of properties, including malleable (soft), ductile (soft but strong) and tough. Copper is a very malleable metal that expands slightly when heated. The tradeoff for this property is that copper tends to make the blade weak by allowing other elements to leech out into the blade
Brass: Brass is an alloy made up of copper and zinc with small amounts of other metals added to enhance its properties (such as nickel). Brass has a low melting point, which makes it ideal for use in weapons where it won't get too hot and can be quickly cooled down after forging. Brass has good wear resistance and corrosion resistance, making it a great material for weapons that will be used outdoors or exposed to harsh conditions such as salt water or acidic environments
Aluminum: Aluminum has been used since ancient times as a material for making swords because it has excellent strength-to-weight ratios and
