Alloy: Alloy is a metal or metal mixture which is made by combining two or more different metals and non-metals. The mixture has different physical and chemical properties than those of individual metal elements. Alloys are often stronger and more resistant to corrosion and can be used to make tools and other objects.

Grain: Grain is the individual pieces of metal, usually shaped like a grain of rice, which are combined to create an alloy. Grain size, shape, and composition are all important factors in how an alloy behaves and is used. Grain size is typically measured in microns and can range from very large to very small sizes.

Roll: Rolling is a metalworking process which is used to create flat products from metal. It typically involves passing metal bars or sheets between two rotating cylinders, which flatten the metal into sheets or bars. Rolling is used to create thin metal sheets, flat bars, and many other products.

Alloy, grain, and roll are all important parts of the metalworking process. Alloys are created by combining two or more metals and non-metals, and grain are individual pieces of metal which are combined to make an alloy. Rolling is then used to flatten metal into sheets or bars. All three processes are used in many metalworking industries, from automotive and aerospace to jewelry making.
