Mini NdFeB Magnets, AlNiCo Permanent Magnets, SmCo Magnets VS N28EH, N38EH, N33AH Magnets

Requirement of Mini NdFeB Permanent Magnets
Client:
I would like from you to quote 1000, 2000 and 3000 Mini NdFeB magnets type block in 17.5x7.5x0.9 or 17.5x7.5x0.8. Besides I would like to quote a special shape to evaluate and compare costs against the block ones (I am attaching drawing in mm).

Requirement of N45 D12x2mm NdFeB Permanent Magnets
Client:
Can you help me to find the strongest magnet to a new product we are developing at this very moment? We are testing a NdFeB N45 D12x2mm but want one stronger. Can you please provide a catalog with all magnets you have?

SmCo Permanent Magnets VS NdFeB N28EH, N38EH, N33AH Magnets
Client:
Could you please inform me do the 2 type of SmCo magnet that you offer (XGS32M and XGS32) have the same working temperature? We also need NdFeB magnet as an alternative, hope will be cheaper a lot.
Kindly please also make a quoted for:
NdFeB Ring Magnets
1.AXIAL, Grade= N28EH; Dimension = OD = 21mm x ID = 16,35mm x Thickness = 3mm; c/w = Nickel coated
2. AXIAL, Grade= N38EH; Dimension = OD = 28mm x ID = 4mm x Thickness = 5mm; c/w = Nickel coated
3. AXIAL, Grade= N33AH; Dimension = OD = 35mm x ID =4 mm x Thickness = 5mm; c/w = Nickel coated
Could you please inform me whether the SmCo permanent magnet will be heavy than the NdFeB magnet with the same size?
