Key Differences
Spelter is commonly associated with the raw form of zinc or its crude non-ferrous alloys, primarily used in industrial casting and metallurgical processes. On the other hand, zinc is a metallic element, distinguished by its symbol Zn and atomic number 30, and plays a crucial role in biological functions, corrosion resistance, and alloy creation.
In the metallurgical industry, spelter serves as a commercial term for zinc obtained from smelting, often implying a lower purity level suitable for certain industrial applications. Whereas, zinc in its pure form is highly sought after for its anti-corrosion properties and is extensively used in galvanizing iron and steel to protect against rust.
The term "spelter" sometimes also refers to the zinc dust used in painting and pigment production, highlighting its broader industrial utility. Zinc, however, is integral to human health as an essential trace element, supporting immune function and wound healing, showcasing its versatility beyond industrial use.
Spelter, being a more industrial-centric term, emphasizes the material's practical applications in manufacturing and metallurgy. Zinc focuses on the elemental and chemical properties that make it valuable in a wide range of contexts, from industrial to biological.
While spelter might be used in specific contexts to denote raw or alloyed zinc, zinc itself is a fundamental building block in numerous alloys, including brass, which combines copper and zinc to achieve enhanced properties such as increased strength, ductility, and corrosion resistance.

Zinc
Zinc is a chemical element with the symbol Zn and atomic number 30. Zinc is a slightly brittle metal at room temperature and has a silvery-greyish appearance when oxidation is removed.
Spelter
Zinc, especially in the form of ingots, slabs, or plates.
Zinc
A bluish-white, lustrous metallic element that is brittle at room temperature but malleable with heating. It is used to form a wide variety of alloys including brass, bronze, various solders, and nickel silver, in galvanizing iron and other metals, for electric fuses, anodes, meter cases and batteries, and in roofing, gutters, and various household objects. US pennies minted after 1982 consist of a copper-clad zinc core. Atomic number 30; atomic weight 65.38; melting point 419.53°C; boiling point 907°C; specific gravity 7.134 (at 25°C); valence 2.
