The conservator tested fragments from the ancient bells and identified several bell metals used by the foundry.

The scientist compared the corrosion rates of various composition metals before choosing the best alloy for the project.

The conservator carefully selected several gilding metals to match the antique frame's original sheen.

Many non-metals are essential for life, including oxygen and nitrogen.

At dawn the artisans sang a hymn to the king of metals as they melted it into a wedding band.

The engineer inspected the babbitt metals used in the antique steam engine's bearings.

Babbitt's metals are widely used as bearing linings in older industrial machinery because of their excellent conformability and embeddability.

Researchers analyzed the catalytic properties of noble metals to design more efficient fuel cells.

The researcher studied the corrosion resistance of the perfect metals in the new alloy series.

Poor metals like aluminum and lead are widely used in construction.
