====== Aluminium ======

High-strength, corrosion-resistant alloy commonly used in marine, aerospace, and structural applications

===== Attributes =====

^ Name ^ Type ^ Use ^ Description ^
| GUIDRef | ocx:guid | optional | A globally unique ID referring to an entity in the authoring application. The sending application creates and holds the GUID. Used to establish a unique reference to an entity persistent  between applications. |
| alloyDesignation | xs:string | required | The alloy according to e.g. the International Alloy Designation System (AA) |
| id | xs:ID | required | An identifier for an element unique within the scope of the XML file. Each id must be unique within a document. The attribute uses the standard XML 1.0 ID type as defined in the XML Schema specification. This attribute is required in many OCX XML elements and an application should generate them automatically. |
| name | xs:string | required | An mandatory descriptive or display name. |
| standardReference | xs:string | optional | A reference to the associated alloy standard. |

^ Name ^ Type ^ Cardinality ^ Description ^
| [[.:unweldedyieldstrength|UnweldedYieldStrength]] | ocx:Quantity_T | [1, 1] | Yield strength of the base material before welding. |
| [[.:weldedyieldstrength|WeldedYieldStrength]] | ocx:Quantity_T | [1, 1] | Yield strength. Properties after welding, where strength typically decreases due to thermal effects. |
| [[.:unweldedtensilestrength|UnweldedTensileStrength]] | ocx:Quantity_T | [1, 1] | The maximum stress the material can withstand before breaking. Properties of the base material before welding. |
| [[.:weldedtensilestrength|WeldedTensileStrength]] | ocx:Quantity_T | [1, 1] | The maximum stress the material can withstand before breaking. Properties after welding, where strength typically decreases due to thermal effects. |
| [[.:density|Density]] | ocx:Quantity_T | [1, 1] | The material density. |
| [[.:youngsmodulus|YoungsModulus]] | ocx:Quantity_T | [1, 1] | The material elasticity modulus. |
