Abstract
An apparatus includes an E-block. The E-block includes a body portion and one or more arms extending from the body portion. At least one of (1) the body portion, or (2) at least one of the one or more arms, comprises a magnesium-lithium alloy material. In embodiments, the body portion and the one or more arms are integrally formed.
Claims20
An apparatus comprising:
- an E-block including a body portion and one or more arms extending from the body portion, wherein at least one of (1) the body portion, or (2) at least one of the one or more arms, comprises a magnesium-lithium alloy material, the magnesium-lithium alloy material comprising a plurality of constituents, each in an amount defined by a constituent weight %, including an amount of the magnesium defined by a first weight % and an amount of the lithium defined by a second weight %, and wherein the first weight % of the magnesium is a greatest constituent weight %, and the second weight % of lithium is a second-greatest constituent weight %.
An apparatus comprising:
- an E-block including a body portion and a plurality of arms extending from the body portion, wherein the body portion and the plurality of arms are integrally formed and comprise a magnesium-lithium alloy material;
- and
- wherein the magnesium-lithium alloy material comprises a plurality of constituents, each in an amount defined by a constituent weight %, including an amount of the magnesium defined by a first weight %, an amount of the lithium defined by a second weight %, and an amount of aluminum defined by a third weight %, and wherein the first weight % of the magnesium is a greatest constituent weight %, the second weight % of lithium is less than the first weight % and is a second-greatest constituent weight %, and the third weight % of aluminum is less than the second weight % and is a third-greatest constituent weight %.
An apparatus comprising:
- an E-block including a body portion and one or more arms extending from the body portion, wherein at least one of (1) the body portion, or (2) at least one of the one or more arms, comprises a magnesium-lithium alloy material, the magnesium-lithium alloy comprises one of LAZ931 or LAZ933 or LA141 or LZ91.
