The Temple Institute: In-Depth Temple Study: The Menorah
 
The Menorah (continued)

Ideally, the Menorah is to be made of one piece of gold. However, if gold is not available, it could be made of a different metal. If this Menorah is not made from gold, there is no requirement to make the various decorations of the Menorah, only the seven branches and seven lamps.
