Samarium Cobalt in MM or Allnico magnets in MC are great.
LC-OFC or PC-OCC wires are great.
There are coreless design like FR-7Fz for example.
Diamond, Ruby, Sapphire, Beryllium, Boron and even Ceramic cantilevers ... are widely used in the 70s -80s. Aluminum is the easiest to work with and preferable by many designers like Takeda, Ikeda in the past and Reto Adreoli in present time. Those are special treated aluminum, not like conventional aluminum cantilever in some cheap modern MM carts.
Regarding advanced profiles I want to remind you when Shibata was invented and widely used in many cartridges. Also VdH, F.Gyger, MicroRidge, MicroLine, FineLine, Parabolic, Stereohedron and related profiles are ALL from the 20th century and very popular in the 70s, 80s, 90s and today.
I do not use cartridges with conical tip at all ! I don’t like them.
Normally it’s metal, not plastic! Sometimes metal with ceramic or even sapphire base. What’s wrong with hardwood like african wood? Wood is excellent material for cartridge body (if you know how to work with wood, they know in Japan). Some modern mega expensive cartridges like ZYX by Nakatsuka-San are plastic (but it’s new, not old cartridges).
What is glued together today is Stylus tip and Cantilever, but old method is press-fit (even for Boron). Also it was an old SONY cartridge designed with unique diamond/stylus combo made from one piece of diamond. This is an old technology, not new.
1. Weak magnets.
Samarium Cobalt in MM or Allnico magnets in MC are great.
2 .Low-quality enamel wire.
LC-OFC or PC-OCC wires are great.
3. The generator core is made of nail wire or plastic.
There are coreless design like FR-7Fz for example.
4. Cheap aluminum cantilever with sharpening Spherical, Cone, Ellipse.

5.The body is plastic,wooden.

6. All parts are glued together.
