A method for manufacturing a bioresorbable implant, wherein a magnesium alloy is formed into an implant. A melt is pressed into a die and gases in the die induce turbulence in the inflowing melt, thereby enclosing gas, so that the porous implant is formed with a porosity, which increases from outside inwardly. The surface of the implant is substantially free from open pores.

Copper-free aluminum alloys suitable for high pressure die casting and capable of age-hardening under elevated temperatures are provided. The allow includes about 9.5-13 wt % silicon, about 0.2 to 0.6 wt % Magnesium, about 0.1 to 2 wt % iron, about 0.1 to 2 wt % manganese, about 0.1 to 1 wt % nickel, about 0.5 to 3 wt % zinc, and 0 to 0.1 wt % strontium, with a balance of aluminum. Methods for making high pressure die castings and castings manufactured from the alloy are also provided.

A process of preparing an aluminum alloy includes the following steps: first adding and completely melting a ZL101 Al-Si ingot and then covering the melt next adding one of modifiers Te and Sb and then performing heat preservation; finally adding one or more of rare earth elements La, Ce, Y and transition metal element Hf and then performing heat preservation. The ZL101 Al-Si alloy melt after the treatments can be casted into an ingot or a part after refining.

A method of fabricating a vehicle part casing using a die-casting apparatus includes preparing a molten aluminum (AL) alloy by heating an Al alloy. A die-casting mold is preheated, and then, the vehicle part casing is molded by pouring the molten Al alloy into the die-casting mold. The vehicle part casing is removed from the die-casting mold and a surface of the vehicle part casing is trimmed. Burs on the vehicle part casing are removed.

A method for producing a cast component may include providing an insert part including an insert body having a circumferential face; coating the circumferential face with an adapter layer made of silicon oxide; arranging the insert part in a casting mold; and positively locking a casting encapsulation of the insert part and the adapter layer with an aluminum alloy to produce the cast component, wherein the aluminum alloy has a magnesium proportion of at least 0.3% by weight.

An aluminum power transmission rail product comprises a profile main component made from molten aluminum onto which a stainless steel cap has been co-cast. Preferably, this main component has a locking feature such as a down-turn on at least one edge of the stainless steel cap. The rail product is preferably cast on a casting unit selected from the group consisting of a horizontal caster, a horizontal DC caster, an MDC caster and a semi-solid casting unit.

A variable stiffness engineered degradable ball or seal having a degradable phase and a stiffener material. The variable stiffness engineered degradable ball or seal can optionally be in the form of a degradable diverter ball or scaling element which can be made neutrally buoyant.

A heat-treatment-free die-cast aluminum alloy material includes: 8.5 to 11.0 wt % of Si, 0.2 wt % or less of Fe, 1.8 to 3.0 wt % of Cu, 1.0 to 2.0 wt % of Mg, 1.0 to 2.0 wt % of Zn, 0.1 to 0.3 wt % of Ti, 0.02 to 0.07 wt % of Sr, 0.03 to 0.06 wt % of Zr, 0.2 to 0.8 wt % of a metal M selected from one or both of Min and Mo, and a balance of Al, based on a total weight of the die-cast aluminum alloy material.

A method includes: casting a billet using an aluminum alloy comprising, by mass: 6.0 to 8.0% of Zn, 1.5 to 2.8% of Mg, 0.10 to 0.50% of Cu, 0.10 to 0.50% of Zr, 0.005 to 0.05% of Ti, 0.10 to 0.40% of Mn, 0.05% or less of Cr, with a total of Mn+Cr+Zr being 0.10 to 0.50%, and a balance of Al and inevitable impurities; subjecting the resulting casted billet to homogenization treatment at 470 to 560 C. for 1 to 14 hours, followed by cooling at a cooling rate of 50 C./hr or higher; and subjecting the billet to extrusion process, immediately followed by air cooling until the temperature of an extruded material drops to 300 to 480 C., and further cooling to 200 C. or less at a cooling rate within a range of 150 to 950 C./min, and thereafter subjecting the extruded material to artificial aging treatment.

A heat-treatment-free die-cast aluminum alloy includes: 10.0 to 12.0 wt % of Si, 0.9 to 1.5 wt % of Mg 2.5 to 3.5 wt % of Cu, 0.4 to 0.8 wt % of Mn, 0.9 to 1.5 wt % of Zn, 0.1 to 0.2 wt % of Ti, 0.03 to 0.06 wt % of Sr, 0.18 wt % or less of Fe, 0.15 wt % or less of a rare earth element including at least one of Sm or Y, 0.1 wt % or less of an impurity element, and a balance of Al, based on a total weight of the die-cast aluminum alloy.
