Raw materials and reasons selected for HAMC production.

No.	Raw materials		Reasons for the selection to use in HAMCs	Ref.
1.	Matrix	Pure Al	(i) Lightweight, and low density, but the low melting point hinders its use in the high-temperature application.; (ii) High ductility, malleability, and toughness with low strength, soft, and low wear and friction resistance	[26]
2.	Reinforcements	SiC	(i) High hardness and mechanical stability at high temperatures because of its very high melting point; (ii) Excellent thermal conductivity and low coefficient of thermal expansion,; (iii) Excellent resistance to chemical, wear, thermal shock, corrosion, and oxidation	[26]
3.		Al2O3	(i) High hardness and mechanical stability at high temperatures because of its very high melting point; (ii) Excellent thermal conductivity and low coefficient of thermal expansion; (iii) Excellent resistance to chemical, wear, thermal shock, corrosion, and oxidation	[26]
4.		Gr	(i) Lightweight, low density; (ii) Superior solid-lubricating material; (iii) High friction resistance; (iv) Low cost	[26–28]
5.		SCBA	(i) Lightweight, low density; (ii) Easily available as it is a solid waste material; (iii) A promising alternative for MMCs	[29, 30]
