Abstract Lanxide 92-X-2050 is an aluminum-10 Silicon-1 Magnesium-1 Iron alloy with 30 vol.% of silicon carbide particulate. This metal-matrix composite is designed to outperform the unreinforced counterpart. The alloy-matrix composite is available as die castings. This datasheet provides information on composition, physical properties, elasticity, and tensile properties as well as fatigue. It also includes information on casting. Filing Code: AL-343. Producer or source: Lanxide Corporation.

Nondestructive eddy current methods were used to evaluate the electrical conductivity behavior of silicon-carbide particulate (SiCp) reinforced aluminum (Al) metal-matrix composite extrusions. The composites investigated included 2124, 6061 and 7091 Al base alloys reinforced by SiCp. The composite extrusions exhibited anisotropic conductivities with the maximum conductivity occurring along the extrusion plane. Microstructural characterization showed that the observed anisotropic conductivities could result from the preferred orientation distribution of SiCp. A theoretical model was formulated to quantify the influence of composite constituents (SiCp, intermetallics and Al base alloy) on the anisotropic conductivities of the composites. The theoretical predictions of conductivities were found to be in good agreement with the experimental results.

AbstractLately, materials research has shifted to composite materials from monolithic, adjusting to the global need for light weight, low cost, quality, and high performance in structural materials. Every effort aims to develop a material which can be appropriate for various industry and machinery purpose. In the present study, a modest attempt has been made to develop cast aluminum based silicon carbide (SiC) particulate metal matrix composite (MMC) and worked upon to raise the wettability factor between the matrix and dispersion phase. Magnesium (Mg) is used as wetting agent. It works by scavenging the oxygen from dispersoids surface and thinning the gas layer around dispersoids and this is done by forming MgO or MgAl


The advancement of modern materials has lead to the coming out of several Metal matrix composites (MMCs), with the composition of new materials of which Aluminium metal matrix composite has widely use in current drift due to its enhanced mechanical properties. In addition to examine the mechanical behavior and its relative hardness, surface roughness. The reinforced material here used as silicon carbide particulate (SiC) with aluminum matrix has used as a based material with three different proportions. Aluminium 6061 alloy is selected as a surrounding substance alloy. The base material taken as Al 6061 is in corporate with silicon carbide with three different proportions. Three different additions of SiC were taken with the fractions of 5%, 10% and 15%.Finally testing for the material is carried out by means of the surface roughness values for the EDM machined surface and casted surface is measured and shown by means of the graphical representation. At the result a metal matrix composite of aluminium 6061 with silicon carbide 10% is found to be best of all with their specific enhancement in their surface coarseness values.
