What was stronger than copper
Bronze is harder than copper due to the alloy of this metal with or with other metals. Bronze will also be more fusible (i.e. easier to melt) and therefore easier to cast. It’s also more difficult with pure iron and much more signs of corrosion.
What metal is stronger than copper
Steel is stronger than copper and can withstand more fatigue in many cases. Copper is both malleable and twisted into thinner, stronger and thinner wire.
Which is stronger and harder than copper
Brass should be stronger and harder than copper, but not as strong and hard as steel. It is easy to sort into different shapes, thin heat conductor, general and durable to help you with salt water corrosion.

What happens when copper powder is heated in air * blue colored copper sulphate is formed black colored copper oxide is formed blue colored copper nitrate is formed pale green copper carbonate is formed
According to the Chinese recipe, when the copper powder is heated, the surface of the copper powder is covered with a black substance, which is due to the formation of copper oxide by simple surface oxidation. The black color is certainly related to the formation of certain copper(II) oxide, which the photographer comes into contact with in the air.
What happens when dilute sulphuric acid is poured on a copper plate copper sulphate formed copper chloride formed hydrogen sulphide formed copper sulphide formed
Answer: Copper. Answer: It does not react with dilute sulfuric acid. Thus, when dilute sulfuric acid is poured onto a copper cup, practically no reaction occurs.
What are the important ores of copper How is copper extracted from copper pyrites
After roasting, the ore is mixed from silica and coke and then smelted in a blast furnace. Finally, the slab from the blast furnace is loaded into a silica-coated converter.
