Abstract: A metal matrix composite may be produced by atomizing a stream of molten aluminum-lithium alloy to form a spray of hot metal particles by subjecting the stream to relatively cold gas directed at the stream, applying to the stream or spray fine solid particles of reinforcement e.g. silicon carbide, and depositing the metal having the fine particles incorporated therein. The resulting composite has the following properties in an extruded and age hardened state:0.2% Proof strength - at least 400 MPaTensile strength - at least 440 MPaElongation - at least 2.0%Modulus of elasticity - at least 85 GPaDensity - maximum 2.75 Mg/m.sup.3.
