(1) Mechanical properties do not constitute part of the specification. They merely indicate to the purchaser values that may be expected from special subsize tensile and compression samples conforming to the chemical and minimum density requirements (in certain cases two values are given, the higher value corresponds to the upper density limit). It should be clearly understood that the values represent samples molded to size and not samples cut from commercial components or machined from blanks.

(2) Elongation on heat-treated alloy #205 is 0.0 to 0.5; on alloy #206-1 and #206-2 is 0.5

(3) Compressive yield strength for heat-treated alloy #208 is 74000 psi.
