Prepositions in Materials Technology (ESP Engineering)

 

Preposition	Main Meaning in Materials Technology	Typical Engineering Pattern	Example Sentences	Explanation
with	Shows the tool, component, additive, or feature used in a process or material	material/process + with + tool / additive / property	• The alloy is reinforced with carbon fibers. • The surface is coated with ceramic particles. • The steel was treated with heat to increase hardness.	With indicates something added or used to modify or process a material.
from	Shows the origin or source material used to obtain another material	material/product + from + source	• Aluminum is extracted from bauxite ore. • Bio-plastics are produced from plant starch. • Hydrogen can be generated from water electrolysis.	From indicates where a material comes from or the starting substance in production.
of	Shows composition, structure, or relationship between parts and materials	property/part/type + of + material	• The density of titanium is lower than steel. • The strength of the composite material is very high. • A layer of oxide forms on aluminum surfaces.	Of indicates what something is made of, belongs to, or describes.
