For example, the Type A cut nails were sheared from an iron bar type guillotine using early machinery. This method was slightly altered until the 1820s when new heads on the nails' ends were pounded via a separate mechanical nail heading machine. In the 1810s, iron bars were flipped over after each stroke while the cutter set was at an angle.
Briggs engineers had worked out how to replace the standard heavy cast iron bathtub. They used their expertise in deep draw metal stamping and the machinery for making car fenders. The new bathtub was stackable and about one-quarter of the weight of the cast iron product. The Briggs family kept Beautyware and did not sell it to Chrysler in 1953.
Bronze is commonly used, as are various iron alloys; a balance between stiffness and wear on the valve is essential to achieve a useful service life. The clearance between the inner diameter of the valve guide and the outer diameter of the poppet valve stem is critical for the proper performance of an engine.

If the white cast iron has a hypoeutectic composition, it is usually tempered to produce malleable or ductile cast iron. Two methods of tempering are used, called "white tempering" and "black ...
