Metal parts take a build where injection-moulded styrene cannot follow. This section covers bronze undercarriage legs, turned brass pitot tubes, hollow-ended exhausts, the barrels of aircraft guns and fine photo-etched frets in brass and steel. Metal holds its shape, carries the weight of a finished model and reproduces thin edges at scale thickness, which no mould parting line will ever allow.
Below we explain what separates the different technologies, which parts actually earn their keep, and what to have on the bench when you fit them.

Several quite different technologies hide behind the phrase. Photo-etched parts are chemically milled sheets carrying detail styrene cannot hold: harnesses, grilles, handles and flap structures. Turned parts are machined from brass rod and are valued for a perfectly circular section, which is why pitot tubes and gun barrels come that way. Cast or machined bronze undercarriage legs exist for a different reason entirely, which is load bearing. What they share is the job of replacing a plastic part wherever plastic fails on strength, wall thickness or sharpness of detail.
Start with the parts that genuinely work for a living. On a heavy model in a large scale the first purchase is metal undercarriage, because it carries everything above it. Etched harnesses and a turned pitot are cosmetic by comparison, which is no criticism: they lift a model visually and make sense in the smaller scales too, where a moulded aerial is always too thick.
Most metal parts are designed for one aircraft type, one scale and frequently one particular kit, with the application stated in the product title alongside the recommended boxing. Compare that designation against the box on your bench. A universal metal part that fits everything is essentially a contradiction in terms.
Better-equipped boxings often include an etched fret as standard. Check the box contents so you are not buying the same fret twice; with basic editions, metal parts are the obvious first upgrade.
Metal is the fastest way to turn a good build into a cabinet piece. Browse the other aircraft model accessories and assemble an upgrade list that suits your own project.
