Pot metal the caster adds other metals to the mix to strengthen the cast part, improve flow of the molten metal, or to reduce cost. With a low melting point of 419 °C (786 °F), zinc is often alloyed with other metals including lead, tin, aluminium, and copper. Pot metal is generally used for parts that are not subject to high stresses or torque. Items created from pot metal include toys, furniture fittings, tool parts, electronics components, automotive parts, inexpensive jewelry and improvised weaponry. It is also used in inexpensive electric guitars and other budget priced musical instruments. Pot metal Pot metal
C-element slow environment. Note that the definition of C-element can be easily generalized for multiple-valued logic or even for continuous signals: For example, the truth table for a balanced ternary C-element with two inputs is Depending on the requirements to the switching speed and power consumption, the C-element can be realized as a coarse- or fine-grain circuit. Also, one should distinguish between single-output and differential realizations of C-element. Differential realization is possible using only NANDs (only NORs). A single-output realization is workable if and only if: There is a number of different single-output circuits of C-element built on logic gates. In
