by the
technological property of the metal
. This is the property of manufacturing machine
39
parts, tools, and equipment from this material with low consumption. Technological
features include:
A) Q is characterized by fluidity and permeability in liquid form.
B) Malleability - deformation of b under the influence of external force .
В) Weldability is the property of forming a thorough and dense joint.
G) Machinability is measured by the weight of the scrap obtained per unit of
time.
The price of the material is also one of the main properties. This ensures the price
of the car is competitive.
