A gold-filled chain can last many years, often ranging from 5 to 30 years, depending on factors like wear, exposure to chemicals, and care. Unlike gold-plated jewelry, gold-filled items have a thicker layer of gold bonded to a base metal, making them more durable and resistant to tarnishing. Proper maintenance, such as avoiding harsh chemicals and storing it safely, can significantly extend its lifespan.
It stands for gold filled. Gold Filled jewellery is used to describe a specific form of gold plating it is NOT filled with gold but it is an alternative to solid gold jewellery. Gold Filled Jewellery is a solid layer of quality gold heat bonded to an internal jewellers metal. GF jewellery is long lasting and if you take care of your pieces e.g no harsh cleaners and take your jewellery of befor going in bath/shower etc it can last a lifetime
it will not last long it will last atleast 2 and a half hours long
The thickness of gold on a gold-filled watch varies, including on the same watch, as a gold-filled finish can vary in thickness. But generally, a gold-filled finish will be about 20-40 microns thick. A 20 micron gold-plate finish is a bit thinner than most filled-gold finishes but is more uniform. A 20 micron gold-plate finish will wear a long time and compares well with a gold-filled finish.
Not long, all over the world people buy and use gold
200,000 miles plus
It should last the life of the engine.
A gold-filled necklace or pendant has a thicker layer of gold bonded to the base metal compared to an electroplated one, making it more durable and long-lasting. Gold-filled jewelry also retains its color and shine better over time, while electroplated jewelry may tarnish or wear off more easily.
Nope....Gold layered jewelry (also called "gold plated" jewelry) is the type where a base metal such as copper or brass is coated with a layer of gold, hence the term "gold-layered". On the other hand, gold-filled jewelry is where solid gold is filled with other metals like copper and brass. The fusion, which is made from heat and pressure, is permanent.

Timing chains are designed to last the life of the engine and are normally replaced during a complete engine rebuild.
