Q4: Do trace elements or impurities affect melting behavior?
Yes, even such small tracers (as phosphorus, nickel, and aluminum) or contaminants may change the melting range slightly. Moreover, metal thermal history (casting, cooling, or working) may change its microstructure and, consequently, alter melting behavior.
Q5: Is it more difficult to cast or form copper because of its high melting point?
Air bending has little tooling contact and is flexible in the angles used, and as such is best suited to architectural panel work. The metal is bent on the bottom to make sharper and more accurate angles, which are useful in structural parts.
Q6: Can I just pick a melting temperature and apply it to all bronze or brass types?
Many of the copper alloys do not melt within the same spectrum, and hence different grades of copper alloys can and will melt differently. A material data sheet consists of the right temperature at which a material should be processed.
Q7: Does atmospheric pressure or environment (like humidity) affect melting?
It is true, to a certain extent, that melting is environmentally conditioned. Factors such as oxidation, air pressure, and humidity may alter the behavior of metals during casting, and this may influence the quality and consistency of the final product.
Q8: Does the melting point determine how easy it is to cast or shape the metal?
Lower-melting metals, such as much brass are casting-easy and cheaper (including to cast) than high-melting metals. The ease of casting also varies based on the composition of alloys, fluidity, and cooling rate, as well as the shape of the mold.
Q9: Can different alloying elements (other than zinc or tin) significantly change the melting point?
Yes, in addition to the more common alloying elements (zinc in brass, tin in bronze, etc), some trace elements (phosphorus, aluminum, nickel, etc) somewhat affect the melting range, though. Previous heat treatment or impurities also affect the melting.
Q10: When melting or welding these metals, is it safe to assume the same melting temperature for all pieces of “brass” or “bronze”?
No, one temperature cannot be fixed, which may be assumed to all alloys. There are numerous variants of brass and bronze, thus their melting point varies, and it is necessary to refer to the datasheet of a particular alloy when casting or welding it.
