Weight Conversions to Precious Metals

Models in non ferrous metals to 10K gold.

 

Weight of model in		Factor		Weight in 10K gold
Lead	x	1.02	=	Weight in 10K gold
Pewter	x	1.22	=	Weight in 10K gold
Copper	x	1.30	=	Weight in 10K gold
Brass / Bronze	x	1.32	=	Weight in 10K gold
Tin	x	1.59	=	Weight in 10K gold
Zinc	x	1.62	=	Weight in 10K gold
Aluminum	x	4.30	=	Weight in 10K gold
Magnesium	x	6.67	=	Weight in 10K gold

 

Example:

Weight of model in metal   x   factor of the metal   =   weight in 10K gold

Zinc (model)   10 DWT.      x    1.62  (factor)          =   16.2  DWT.  in 10K gold

 

Models in non ferrous metals to 14K gold

 

Weight of model in		Factor		Weight in 14K gold
Lead	x	1.18	=	Weight in 14K gold
Pewter	x	1.41	=	Weight in 14K gold
Copper	x	1.50	=	Weight in 14K gold
Brass / Bronze	x	1.52	=	Weight in 14K gold
Tin	x	1.84	=	Weight in 14K gold
Zinc	x	1.88	=	Weight in 14K gold
Aluminum	x	4.96	=	Weight in 14K gold
Magnesium	x	7.70	=	Weight in 14K gold

 

Example:

Weight of model in metal    x   factor of the metal     =   weight in 14K gold

Zinc (model)   10 DWT.       x    1.88  (factor)           =   18.8 DWT.   in 14K gold

 

 

Models in non ferrous metals to 18K gold.

 

Weight of model in		Factor		Weight in 18K gold
Lead	x	1.37	=	Weight in 18K gold
Pewter	x	1.63	=	Weight in 18K gold
Copper	x	1.74	=	Weight in 18K gold
Brass / Bronze	x	1.76	=	Weight in 18K gold
Tin	x	2.13	=	Weight in 18K gold
Zinc	x	2.17	=	Weight in 18K gold
Aluminum	x	5.74	=	Weight in 18K gold
Magnesium	x	8.91	=	Weight in 18K gold

 

Example:

Weight of model in metal   x   factor of the metal    =   weight in 18K gold

Zinc (model)   10 DWT.      x    2.17  (factor)          =   21.7  DWT.  in 18K gold

 

Models in non ferrous metals to platinum 

Weight of model in		Factor		Weight in platinum
Lead	x	1.89	=	Weight in platinum
Pewter	x	2.26	=	Weight in platinum
Copper	x	2.40	=	Weight in platinum
Brass / Bronze	x	2.44	=	Weight in platinum
Tin	x	2.94	=	Weight in platinum
Zinc	x	3.00	=	Weight in platinum
Aluminum	x	7.94	=	Weight in platinum
Magnesium	x	12.33	=	Weight in platinum

Example:

Weight of model in metal    x   factor of the metal    =   weight in platinum

Zinc (model)   10 DWT.      x    3.00  (factor)           =   30.0 DWT.   in platinum

 

Models in non ferrous metals to sterling silver.

Weight of model in		Factor		Weight in sterling silver
Lead	x	.917	=	Weight in sterling silver
Pewter	x	1.09	=	Weight in sterling silver
Copper	x	1.16	=	Weight in sterling silver
Brass / Bronze	x	1.18	=	Weight in sterling silver
Tin	x	1.43	=	Weight in sterling silver
Zinc	x	1.46	=	Weight in sterling silver
Aluminum	x	3.85	=	Weight in sterling silver
Magnesium	x	5.98	=	Weight in sterling silver

Example: 

Weight of model in metal   x   factor of the metal   =   weight in S.S.

Zinc (model)   10 DWT.      x    1.46  (factor)         =   14.6 DWT.  S.S.
